UPDATE. (Issued 955 AM CST Fri Mar 5 2021)
Forecast details remain on track today. Areas of mid to high level clouds will likely graze areas from Madison westward. There is also the potential for some local high temperatures to over perform today. High temps for this afternoon may be adjusted upward a degree or two.
SHORT TERM. (Issued 328 AM CST Fri Mar 5 2021)
Today through Saturday Night:
A dry period of weather is expected across the area, with strong high pressure west of Hudson Bay today into this evening slowly moving southeast across Ontario later tonight into Saturday night.
Main forecast uncertainty lies with clouds and temperatures today into Saturday. Current area of middle level clouds across northern Wisconsin is trying to slide southeast toward and into northern parts of the area. Not sure how much of this, if any, will move in this morning. It may become more scattered out if it does make it into the area. Kept cloud cover on the low side, but will watch trends and make adjustments if needed.
May see some diurnal stratocumulus develop this afternoon with daytime heating. Highs should reach into the middle 40s over most of the area, with a little cooler readings near the lake. Went towards the 75th percentile of the NBM today, as it has been struggling with the recent mild days.
Models bring a weak cold front southward through the area later tonight, with some possibility for low clouds and light fog to develop with this feature. Forecast soundings are showing some potential for the boundary layer to saturate, more so on the NAM than the GFS. For now, will keep scattered clouds in the forecast, as there is some uncertainty with how widespread any low clouds may be. Left light fog out of forecast for now.
Skies should clear out by later Saturday morning and linger Saturday night. Highs Saturday will be a little cooler than Friday, with slightly cooler 925 mb temperatures behind the weak cold front. Lows in the upper teens to lower 20s are expected inland tonight and Friday night, with milder values close to the lakeshore.
LONG TERM. (Issued 328 AM CST Fri Mar 5 2021)
Sunday through Thursday:
We'll end the weekend with the start of a more significant warm up, as the persistent high pressure to the N/NE of the area gets pushed out, and is replaced by increasing W/SW flow. A system moving N/NE through the northern Plains into Canada will help to push the cooler surface high out.
Then, upper ridging builds over the region, with 850/925mb temps really warming up with values closing in on 7C. As mentioned above, Sunday will be the transition, and with models not handling these warmer days in the past, have nudged the forecast towards the 75th percentile of the NBM. That puts highs on Sunday close to 50 for much of the area, the exception is going to be closer to the lake where the SE winds off the water may keep highs in the lower 40s.
By Monday, we should start to see the stronger W/SW flow dominate, and highs into the 50s are forecast. Some of the more inland locations could see the first 60 of the year. Best chance for widespread 60 degrees will be on Tuesday, though current forecasts are still a little on the cool-side, so have nudged the forecast towards the 75th percentile for highs.
Any snow that is left on the ground next week may be gone pretty quick, with a fairly persistent period of temps above freezing. Overnight lows may not drop back below freezing until the latter half of the week.
Starting Tuesday evening through Wednesday, the upper ridge starts to slowly move eastward, and with a trough digging across the western US, we'll see a few shortwaves get ejected out of that system and move into the Upper Midwest. Rain may start as early as Tuesday night, with all guidance pointing to more widespread showers and maybe even a few rumbles of thunder on Wednesday.
Some differences remain on when exactly we'll see a cold front move through, but the front does appear to stall somewhere in the vicinity Wed/Thu/Fri, and with a stronger wave moving through Thu/Fri, there could be a threat for some higher rainfall amounts depending on exactly where that front stalls.
Luckily, we should have melted much of the snow, and we won't be adding that water equivalent amounts to whatever we get next week. But the ground is still likely to be a mixture of frozen and still very saturated from the slow snow melt. So, anything that does fall may end up as more runoff than anything else, and will be something to watch for any flooding potential next week.
Unfortunately, these warmer temps won't last, with the front moving into the OH Valley and winds switching to the N/NW. Cooler temps are expected to end the week and continue into next weekend.
AVIATION. (Issued 955 AM CST Fri Mar 5 2021)
High pressure will continue to contribute to modest northwesterly winds which will become more northerly tonight as a cold front sinks southward tonight. VFR cigs and vis are expected today and through tonight. Sky cover may increase for a short period overnight as the cold front moves through, but impacts to cig category should be minimal.
MARINE. (Issued 328 AM CST Fri Mar 5 2021)
Strong high pressure will remain just west of Hudson Bay today into this evening, before shifting southeast across Ontario later tonight into Saturday night. Northwest to north winds are generally expected today, becoming mainly north tonight into Saturday.
Winds should shift to the south on Sunday, with south to southwest winds into next week. These winds may become gusty at times in the early to middle portions of the week. At this time, the best chances for Small Craft Advisory conditions appear to be Tuesday night into Wednesday.
