Area Forecast Discussion National Weather Service Milwaukee/Sullivan WI 1128 PM CST Sat Feb 22 2020

UPDATE.

Slight breezes continue this evening and this is helping to slow the drop in temps tonight. Made tweaks to trends but the rest of the forecast is on track.

AVIATION(06Z TAFS).

A brief period of LLWS is possible through 08z tonight as a 30-40kt low-level jet moves across southern WI. Winds will stay out of the SW for much of the period but gusts won't be nearly as high on Sunday. VFR conditions are forecast through the period. A dry cold front will move through between 00-06z Sunday night into Monday and winds shift to the NW. There is some indication that a lower cloud deck could develop as the shallow cold layer moves in but confidence in that is low.

PREV DISCUSSION. (Issued 848 PM CST Sat Feb 22 2020)

UPDATE .

The current forecast is on track and no changes are needed at this time. Patchy fog is possible tonight especially in any wind sheltered locations. Expect lows to bottom out in the upper 20s to lower 30s.

MARINE .

Breezy southerly winds continue with gusts up to 20 to 25 knots tonight. The current forecast is on track and no changes are needed at this time.

PREV DISCUSSION . (Issued 510 PM CST Sat Feb 22 2020)

UPDATE .

High clouds moving through this afternoon will give way to clear skies tonight. Better moisture was able to work it's way into the region today with dewpoints sitting in the mid to upper 20s, which is about +10 degrees above yesterday. As we decouple tonight and lighter winds develop it's possible that some patchy fog develops overnight. The warmer weather today did allow for more snow melt and that could provide the needed low level moisture for fog tonight. Will update the wx grids to show some patchy fog and monitor trends overnight.

AVIATION(00Z TAFS) .

Passing high clouds at 20,000ft shift east this evening leaving VFR conditions. However, the addition of some low level moisture tonight could lead to patchy fog development. Guidance has backed away from the low/mid level clouds moving into the region with a weak trough Sunday morning and with drier air aloft think that reasonable. A period of LLWS is expected from 02-08z as a 35-40kt LLJ moves across southern Wisconsin. Lighter winds are forecast for Sunday.

PREV DISCUSSION . (Issued 323 PM CST Sat Feb 22 2020)

SHORT TERM .

Tonight through Sunday Night . Forecast Confidence is High.

Temperatures are running on the highest side of guidance today, around 40 but hitting mid 40s in a few spots. This is similar to what the ECMWF, CONSMOS, and CanadianNH models suggested for today. The 925mb temps are going to be higher Sunday than they were today, but we could have a little more cloud cover. Therefore, I played it conservative with temps for tomorrow, with highs more toward the mid 40s (upper 40s in southeast WI). Several models have temps more toward 50 tomorrow and it will ultimately depend on sky cover.

A period of low clouds is possible Sunday morning due to low level warm air advection ahead of a surface trough approaching. At this time, I do not see any upstream obs suggesting this and the low level moisture may be overdone in the models. The air will be very dry just above 3000 ft, so there is not a lot of confidence in the higher cloud cover scenario panning out.

It will be a fairly mild night tonight with lows around 30 and steady south-southwest winds. A surface trough will slide through southern WI Sunday afternoon, bringing a wind shift to the west, along with a cooler air mass for Sunday night. Lows will be in the lower to mid 20s. Lighter winds are expected, but minimum wind chill values will be in the mid to upper teens.

LONG TERM .

Monday . Forecast Confidence High .

Upper-level ridge pushes east as two systems approach the Midwest from the west-northwest and another form the southwest. Winds are expected to shift easterly through the day with increasing cloud cover. Temps will be a few degrees cooler than the weekend given the increasing clouds, but are expected to top off in the upper 30s.

Monday Night Through Wednesday . Forecast Confidence Low .

A complicated winter setup is expected with this incoming system early next week as a mid-level trough/surface low working in from south-central Plains merges with another mid-level trough coming in from the northern Plains. Low-level dry air looks to hold on a bit longer Monday evening, thus have delayed the onset of precip to overnight Monday into Tuesday.

Otherwise, models are in general agreement with a merger of these systems Tuesday, but timing and track varies. The latest GFS have the merger of these systems a bit further west and earlier, which pivots the surface low approaching from the southwest up and along the IN/IL border. The more westerly track may result in higher QPF/snowfall amounts across our northern counties in central WI. While periods of wintry mix of rain and snow will be possible across the southeast WI as some above freezing surface to 900mb temps work their way into the area, thus limiting snow amounts across the southeast Tuesday. However, snow is expected to return overnight Tuesday and Wednesday as another round cyclogenesis occurs as the first surface low weakens and another low develops on the backside (e.g. dual low setup).

On the other hand the 12z ECMWF as well as the 18z NAM progs a similar trend, but a bit later and further east. This looks to bring the surface low from the southwest up along the IN/OH border, thus pulling the moisture a bit further east and south. This setup will likely limit any rain/snow mix to occur and result in higher QPF/snow amounts further south across southern WI.

Nonetheless, can expect a winter system to bring accumulating snows across southern WI beginning as early as late Monday night, with the bulk of the snow on Tuesday, and a lingering into Wednesday before the mid-level trough pushes eastward. This prolonged snow event is likely to cause impacts to travel, especially on Tuesday. However, given the variations in model tracks and if any low-level warm air will intrude into the area, snowfall totals remain uncertain at this time.

Thursday and Friday . Forecast Confidence Medium .

Drier and colder conditions are expected for the later half of the week as winds shift to the north-northwest and high pressure builds behind this early week system.

AVIATION(21Z TAFS) .

An area of high clouds will stream across southern WI through mid evening. After clear skies overnight, there is a possibility for stratus clouds in the morning, just ahead of a weak surface trough passing through. If they develop, these should be VFR with ceilings around 3500 ft, but there is a chance for slightly lower.

From mid evening through late tonight, a period of low level wind shear is expected due to southwest winds up to 40 kt just above the surface.

MARINE .

Gusty southwest winds will persist through Sunday, though gusts are expected to remain below Small Craft Advisory levels. Some gusts to 30 knots may occur at times over northern portions of the open waters of Lake Michigan during this period. Winds should weaken Sunday night as a surface trough moves through the region.

Low pressure will strengthen as it moves from the southern Plains into the northeastern part of the country Sunday night into the middle of next week. Northerly winds over Lake Michigan will gradually increase later Monday, then become northwest on Thursday. Higher waves are expected Monday night through Wednesday.

Winds and waves should reach Small Craft Advisory levels Monday night into Wednesday/Thursday. Gales look a little less likely at this time, though gusts to 30 knots remain possible at times during this period.
