Quickly warming back up... Spring Fever by middle next week

After a relatively cool day today (well, cool compared to what we have had lately) the weather will quickly warm back up, reaching a high of 54 on Friday with a mix of clouds and sun along with blustery southeast winds.

A chance of rain moves in Friday Night into Saturday, leaving highs around 52 on Saturday. Rain should push out by Sunday, leaving it sunny through at least the middle of next week. Highs will continue to increase, lower 50s on Sunday, middle 50s on Monday, around 60 on Tuesday, before leaping into (at least) the middle 60s for Wednesday and Thursday.

There is a chance that we could see highs around 70 by the end of the week, along with a chance of thunderstorms! Spring fever will definitely be in swing by this time next week, and we will be looking back at March as only the seventh time in St. Cloud history that we have gone without any snow falling, along with one of the top 10 warmest Marches ever.

Photos of the Mississippi Ice Jam, Sauk River Flooding, and the Hennen's FAIL!

The girlfriend and I went on an adventure today to the site of the Mississippi Ice Jam along with a park where the Sauk River is flooding. Here are some of the pictures we captured (links will take you to the whole photo album):

THE NATIONAL WEATHER SERVICE IN THE TWIN CITIES HAS ISSUED A

* FLOOD WARNING FOR ICE JAM FLOODING IN...
  EAST CENTRAL STEARNS COUNTY IN CENTRAL MINNESOTA...
  WESTERN BENTON COUNTY IN CENTRAL MINNESOTA...

* UNTIL 1030 AM CDT FRIDAY

* AT 1030 AM CDT...EMERGENCY MANAGEMENT AND LAW ENFORCEMENT REPORTED
  A SIGNIFICANT ICE JAM ALONG THE MISSISSIPPI RIVER FROM THE NORTH
  SIDE OF SARTELL NORTHWARD THROUGH PINE POINT. THIS IS CAUSING
  WATER TO BACK UP ALONG THE RIVER AND INTO LITTLE ROCK LAKE. LAW
  ENFORCEMENT HAS REPORTED SEVERAL HOMES ON PINE POINT ARE ALREADY
  CLOSE TO BEING IMPACTED. FLOODING IS LIKELY IN IMMEDIATE LOWLAND
  AREAS ALONG THE RIVER AND POSSIBLY ALONG HARRIS CHANNEL AND INTO
  LITTLE ROCK LAKE. IF THE ICE JAM WERE TO BREAK ABRUPTLY...FLOODING
  IS LIKELY TO OCCUR FURTHER DOWNSTREAM ALONG THE MISSISSIPPI
  CHANNEL THROUGH SARTELL AND POSSIBLY INTO THE NORTH SIDE OF ST
  CLOUD. CONSIDERING THE EXTENT OF THIS ICE JAM AND LITTLE ICE
  MOVEMENT HAVING BEEN NOTICED THUS FAR...THIS ICE JAM MAY BE A
  PROLONGED EVENT.

* SOME LOCATIONS THAT ARE LIKELY TO EXPERIENCE FLOODING
  INCLUDE...PINE POINT...LITTLE ROCK LAKE...WATAB...SARTELL AND SAUK
  RAPIDS.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

RESIDENTS NEAR THE MISSISSIPPI RIVER FROM JUST SOUTH OF RICE TO
THE NORTH SIDE OF ST CLOUD SHOULD ACT NOW FOR POSSIBLE FLOODING
AS THE ICE MOVES THROUGH THE RIVER.

Latest on the Sauk... Warm through tomorrow before a change...

The Sauk River is currently quickly approaching 7', a foot above flood stage. It is expected to level off there sometime within the next 24-36 hours before slowly going back down. While the forecast has the waters slowly receding, there is always the possibility that a surge could send the river back up. Seven feet is a moderate flood for the Sauk.

Meanwhile, the Red River to the north is in moderate to major flood stage in the Fargo and Grand Forks area. It is expected to crest at 38' in Fargo by the end of the weekend (3' below last years record crest) and at 48' in Grand Forks (just over a foot below last years record crest).

Most of the snow has already melted off, and the last bits of it (besides the huge mounds) should be gone by the end of the week. We reached a high of 53 on Wednesday, but should approach 60 Thursday.

After that, temps (and somewhat the weather) take a downturn. We will see a system that comes in from the north, bringing temps back to the 30s and lower 40s on Friday. A snow chance that was in the forecast has been taken out, as it looks like the precipitation will stay mainly south of the Twin Cities and mostly affect areas like Iowa and Kansas. We'll get back into the 40s next week before a mix bag of precipitation (rain/snow/freezing rain/sleet) moves in Tuesday through Wednesday. After that, trends show a very slow warm up, with maybe a rain chance for the end of the month.

URGENT: Sauk River to spill over banks later today... Moderate Flooding Expected


River depth and expected flood forecast as of 10 AM Tuesday by the NWS

The Sauk River unexpectedly rose a foot overnight, leaving it precariously just below flood stage this morning. It is expected that the Sauk will rise over the banks later today before possibly cresting around 7.0' on Thursday. A depth of 7' is considered a "Moderate Flood" for the river, and a good foot above flood stage. A Flood Warning in now in effect until further notice for the Sauk River in St. Cloud.

Continued chances of rain before sun comes back... Latest flooding information (including the Sauk, Mississippi, and Red Rivers)

Overnight tonight we will see a chance of light rain with areas of fog, lows reaching 36. Sunday will see fog early, cloudy through the day and high of 50. Rain chances again Monday and Tuesday with highs in the upper 40s around 50 before the sun breaks out for Wednesday/Thursday and highs get into the lower 50s. Rain comes back into the forecast Friday, with the chance of some s*n*o*w on Saturday.

Here is a list of all the Flood Advisories out for the Twin Cities watch area:

For more on these, check out the NWS Chanhassen Flood Briefing Page, where you can read the statements and find graphics referring to current and forecasted river levels along with precipitation forecasts.

An update on the Sauk River... I would expected a Watch/Warning to be issued within the next few days. According to NWS forecasts, the Sauk River near St. Cloud is expected to approach Minor Flood Stage by the end of next week. Meanwhile, the Mississippi at St. Cloud State will also be approaching Action Stage by the end of the week. As the week goes on I will attempt to bring pictures/video from the rivers as the Spring Flooding Season continues.

And for those up in the Red River Valley, the NWS Grand Forks has also set up a Flood Briefing Page. The Red River is expected to reach Major Flood Stage along its entire path, including Wahpeton, Fargo, and Grand Forks, and could approach the historic levels set just last year.

Dense Fog Advisory through 9 AM -- More Rain through Weekend -- Latest Flood Watches/Warnings


Look! We have Lake Front Property for the next few weeks!

Once again, we have a Dense Fog Advisory out until 9 AM like we have had most days this past week. All the rain/melting snow along with temps staying above freezing (allowing more melting) is creating the endless dense fog-at-night situation for the moment. Complete advisory at the bottom of post.

I actually have some good news on the rain front! We should experience some more periods of drizzle and rain through the rest of the weekend, but then I think we will shed the rain and clouds and bring some SUNSHINE for next week! Woo! And with that will come warm(er) temps, with highs reaching the lower 50s by Tuesday. Temps over the weekend, though, should be in the middle 40s for highs.

Looking ahead (though I really don't want to), we see a possibility of some snow mixing back in next weekend. Take it with a grain of salt, as I don't want to put any trust in it at the moment.

Tonight Dense fog and drizzle, 35. Saturday Drizzle, early fog, 46. Sat Night Drizzle and fog likely, 36. Sunday Rain possible 47. Monday Mix of clouds and sun, 47.

Steams and rivers continue to rise, causing A LOT of Flood Watches and Warnings in the area. This is the list I could come up with (I may have accidentally left out locations -- there are just SO MANY at the moment!). Even though the Sauk is not listed, we need to watch it closely... and probably the Mississippi River shortly.

Flood Warning (all until further notice unless noted):
  • NORTH CENTRAL SCOTT COUNTY IN EAST CENTRAL MINNESOTA UNTIL 700 AM CST SATURDAY DUE TO AN ICE JAM ON SAND CREEK (INTERESTS FROM JORDAN TO CARVER SHOULD BE AWARE OF RIVER RISES)
  • MINNESOTA RIVER AT SAVAGE AFFECTING DAKOTA...HENNEPIN AND SCOTT COUNTIES

Dense Fog Advisory through 9 AM Thursday... Rain through Saturday... Watch for Flooding


NWS Chanhassen Watches/Warnings as of 3 PM Wednesday... Gray is Dense Fog Advisory... Lime green is Flood Warning... Dark green is Flood Watch

A series of storms will be affecting the area throughout the beginning of the weekend, leading to many days with periods of rain over the whole area. By the end of the day on Saturday, a half an inch to an inch of rain is possible throughout most of the area from the systems.

These systems will keep the temps above freezing during both the day and night, with highs in the lower to middle 40s and lows in the middle to upper 30s. This will allow for continued rapid snow melt, and I would not be surprised if most snow (except for larger piles) will be melted away by the end of the weekend. One thing we will have to watch out for is rising rivers, especially along the Sauk locally. Meanwhile, a Flood Watch has already been issued for the South Fork Crow River below the town of Mayer affecting Carver County due to the rain and melting conditions.

A Dense Fog Advisory is in effect for parts of Minnesota, including Stearns County, until 9 AM Thursday. Check the statement below for the details.

Forecast Hiatus: School and Medical

Yes, we are only a few days into this, but already a break is needed. The past few days there hasn't been a forecast due to more important school tests. The next few days there won't be one either -- I am going in for a medical procedure on Tuesday and am going to take the weekend and (at least) first half of the week off of forecasting to concentrate on the more important things. Should hopefully return to forecasting sometime later next week.

Melting Continues Throughout Next Few Days... Watching the Air Quality

Nice warm, sunny, hazy weather will continue over the next few days as we stay stuck under a high pressure system. The main concern because of that, though, will be the air quality. We will continue to have light winds, therefore not that much mixing, which will allow higher pollution levels as we get into the second half of the week. Air quality is currently hovering around the low moderate range, but could approach the high end of that scale after the rush hour tonight and into the next few days. Be prepared for air quality alert days by the end of the week. Highs through the weekend will be in the upper 30s around 40.

We will see a system move in Friday Night into Saturday -- it will be lacking moisture though. There is a good chance that most of what falls will be a mixture of rain/snow or freezing rain, and that it won't be much.

Steering currents want to put more systems back over our area as we get into next week. I'm on a wait-and-see approach right now about it. I'm still not confident about our "storm" next Monday and Tuesday -- count on probably seeing some moisture, but I'm not sure it will swing up far enough to get most of Minnesota in a good storm that we haven't seen in a while. (I wouldn't mind continuing to see the southland and northeast hit by the storms... I'm ready for no more snow!).

Tonight: Clear with some fog, low around 15. Wednesday: Fog in morning, turning sunny, high around 40. Thursday: Fog in morning, turning sunny, high around 40.

Beautiful start to spring... But melting leads to flooding...

We are going to try and revive my blogging! Woo! For those of you who have followed my blogs for years, you know that I would offer a detailed nightly forecast. Since then I had turned to mainly event-blogging (mainly Winter and Severe Storms). Well I am going to try and mix the old with the new... bring back daily weather thoughts (maybe not complete forecasts or very detailed, but enough to get you through the next day or so) with more detailed writings for the big weather events. We can build this blog together!

Ah, a beautiful day for the start of Spring! Birds chirping, bright blue sky with a bright yellow ball in the middle of it, temperatures in the middle 30s... Yes, a day where t-shirts are actually out in full force. We should enjoy this weather continuing through the rest of the week with highs approaching 40 especially towards the end of the week. We will continue to melt the snow pack that we do have, but just remember that anything that ponds up during the day and doesn't run off will freeze overnight, so take it safe on the roads in the mornings. We have a chance of a little rain/snow on Saturday, but I'm definitely not expecting much.

We are watching a potential system for the beginning of next week; latest model runs have that sagging southward at the moment. It is still something to keep an eye on, though.

Of course, melting is occurring at the moment -- we are down to approximately 11" of snow on the ground in STC, but there continues to be a deep snow pack to our south and west, ranging over 2' in areas. Updates within the past week (click on the links for more information) show that there is a good chance of flooding at Montevideo and also the Mississippi River below the junction with the Minnesota River (St. Paul and Hastings); the Crow River at Delano has a large chance of flooding; the Mississippi River above the Minnesota River (i.e. our area) has a 20-40% chance of flooding. Meanwhile, the chance of major flooding along the Red River has increased to 80% in the Fargo-Moorhead area and 60% in the Grand Forks area. While the conditions of the past few days have been ideal melting conditions to minimize the threat, any addition of moisture or rapid increase in temperature will likely increase all these flooding percentages. Also, temperatures in SW Minnesota haven't been able to get as high as we have the past few days, therefore they haven't been able to melt as we have been, leading to a lot more increased melting for them as the weeks go on.

Already today, sandbagging is occurring in Fargo and Grand Forks in anticipation of the upcoming flooding which has the potential to come close to last years historic flooding of the Red River. Stay tuned in upcoming weeks for the latest.

Forecast: 10-15 tonight with clear skies. Around 35 Tuesday and continued sunshine.
