Area Forecast Discussion . UPDATED National Weather Service Milwaukee/Sullivan WI 1154 AM CST Tue Jan 21 2020

UPDATE.

We are warming up quickly this morning, despite the cold start, due to warm air advection with return flow around the high. Southwest winds are also increasing, and they will become more gusty through the afternoon.

AVIATION(18Z TAFS).

Look for increasing southwest winds this afternoon that will persist into Wednesday evening. LLWS is expected tonight with strong southwest winds just above the surface. VFR ceilings and visibility are expected through Wednesday morning. MVFR conditions will begin to develop Wednesday afternoon as light snow spreads into the area.

PREV DISCUSSION. (Issued 858 AM CST Tue Jan 21 2020)

UPDATE .

No change to the forecast for today.

AVIATION .

Look for increasing southwest winds this afternoon that will persist into Wednesday evening. VFR is expected through Wednesday morning. MVFR conditions will begin to develop Wednesday afternoon as light snow spreads into the area.

MARINE .

Expect increasing southwest winds this afternoon into tonight with departing high pressure. Gale force gusts are expected for most of the north half of Lake Michigan from this evening through Wednesday evening. A Gale Warning is in effect. A Small Craft Advisory is in effect for the nearshore waters beginning later this afternoon into Wednesday afternoon.

PREV DISCUSSION . (Issued 524 AM CST Tue Jan 21 2020)

UPDATE . No changes to forecast at this time.

PC

AVIATION(12Z TAFS) . VFR mostly SKC into tonight with high pressure shifting from Iowa into the OH Valley. Models trying to develop some patchy fog early this morning. All in all a tightening pressure gradient will set up between the retreating high and encroaching low pressure trough in the Plains. ahead of a trough in the Plains. So a sustained southwest wind will develop today and then amp up tonight into Wednesday.

PC

PREV DISCUSSION . (Issued 308 AM CST Tue Jan 21 2020)

SHORT TERM .

Today and Tonight - Confidence . Medium to High

Clear, cold dry air in place thanks to a high pressure system across Iowa. This will trend east/southeast into the Ohio Valley and set up a southwest return flow as the day wears on. Should see temps deeper into the 20s. Overnight temps won't drop off as much due to the sustained southwest winds. Overall, guid temps look ok.

LONG TERM .

Wednesday through Saturday . Forecast Confidence is Medium.

An unsettled pattern is shaping up from mid-week to early in the weekend with multiple periods of light precipitation. Temperatures won't vary much from day to day and will be mild side compared to normals for this time of year with lows in the upper 20s and highs in the low to mid 30s. Guidance has come into better agreement with the overall pattern into the weekend but some subtle variations could impact precip totals. QPF amounts due to previous uncertainty were advertising lower amounts and with a bit better agreement we've nudged amounts up compared to previous forecast. However, we are likely still on the low side and think something closer to what the GEFS mean has for QPF totals through Saturday are reasonable (0.4-0.6 inches).

The ridge currently to the south of the region pushes east tonight into Wednesday and two shortwaves move out of the Rockies and into the upper Midwest. Strong WAA and increasing moisture advection will result in temperatures quickly warming through the day Wednesday towards the freezing mark. Temperature profiles initially indicate a warm nose aloft over the region with a fairly dry low/mid levels. As the shortwave and moisture begin to arrive this layer cools and the entire profile is below freezing by Wednesday afternoon. Could see a brief window where some freezing drizzle is possible in the west before the better deeper moisture arrives Wednesday morning. Then light snow will spread from west to east during the afternoon and evening hours. Given the temperature profile this should by more of a wet type of snow but still on the lighter side. Snow accums for this first round should stay around an inch in the west and lower amounts as you go east.

These initial shortwaves quickly move away from the region and attention then turns to a trough digging into the central US which eventually becomes a closed low over the OH Valley on Friday. While we are in between these two systems we may see a brief break in light snow on Thursday. But with little change to the moisture profile aloft it's not out of the question to see the light snow continue. By Thursday night as the upper low begins to deepen and close off precip will be spreading back into the region from south to north. Now one question is that as this system deepens it will be advecting warmer temps towards southern WI and with surface temps warming to just above freezing a brief change to light rain is possible Friday morning. In terms of totals during this period they will be highly dependent on where the low tracks. Most of the models suggest a west to east movement from central MO along the OH River into southern OH. However, some guidance has a track slightly further north, which could bring some of the higher QPF numbers a bit more into our region. In either case, expect a more light to moderate period of snowfall for Friday into Saturday morning. The system departs to the east Saturday morning and snow will end from west to east.

Saturday night through Monday . Forecast Confidence is Medium.

The latter half of the weekend and into early next week will stay with the more mild temperature trend with highs in the low to mid 30s and lows in the mid to upper 20s. A few weak waves move across the US/Canada border during this period but with limited moisture not expecting much in the way of any precip other than a few flurries.

AVIATION(09Z TAFS) .

VFR mostly SKC into tonight with high pressure shifting from Iowa into the OH Valley. Will keep an eye on patchy fog trends early on. Models trying to develop some patchy fog early this morning. All in all a tightening pressure gradient will set up between the retreating high and encroaching low pressure trough in the Plains. ahead of a trough in the Plains. So a sustained southwest wind will develop today and then amp up tonight into Wednesday.

MARINE .

High pressure spreading into the Great Lakes from the Northern Plains will bring light winds to the region through this morning. Expect increasing southwest winds this afternoon into tonight with the departing high. Gale force gusts are possible over the north third of Lake Michigan tonight through Wednesday. Thus the Gale Watch has been converted to a Gale Warning. A Small Craft Advisory has also been issued for the nearshore waters beginning later this afternoon into Wednesday afternoon.

MKX WATCHES/WARNINGS/ADVISORIES. WI . None. LM . Gale Warning from 6 PM this evening to 9 PM CST Wednesday for LMZ261-362-364-366-563-565.

Small Craft Advisory from 4 PM this afternoon to 4 PM CST Wednesday for LMZ643>646.
