The forecast remains on track.

SHORT TERM. (Issued 312 AM CDT Thu Apr 22 2021)
Today through Friday:
A few patches of clouds will continue to work their way across western portions of the CWA this morning and cannot rule out a light flurry or two from it. However, any precip will have to overcome the very dry air, so most will likely evaporate before reaching the ground as is evident via the lack of reports in the latest surface obs under the cloud deck.
Otherwise, today will be mostly dry and warmer as surface high pressure skirts to our south and mid-level ridging develops across the Upper Midwest. Expect to see temps rise closer to normal with west to southwest winds. Looking at highs to top off in the 50s with a few locations cracking into the low 60s. Drier conditions will continue overnight with lows in the mid to upper 30s.
Meanwhile, a mid-level shortwave trough is progged to work its way across the Central Plains today and push into the Upper Midwest for Friday. This wave will bring a swath of vorticity along with a weakening band of 700 mb frontogenesis into WI Friday. The forcing combined with increased PWATs around half an inch is expected to be enough for increased shower activity. Looking like the scattered rain showers will be mostly light as the GEFS and EPS ensemble members are showing QPF to range from a few hundredths to maybe a tenth of an inch or two at most. Overall, nothing too exciting with this wave Friday.

LONG TERM. (Issued 312 AM CDT Thu Apr 22 2021)
Friday night through Wednesday:
A weak upper trough will bring a slight chance of showers Friday night and Saturday. Any precipitation would be very light. Dry weather is expected Sunday as high pressure moves across the state.
Warmer temperatures are in store starting Monday with mid level ridging and southerly flow. A front will move through midweek bringing widespread rainfall. A deep midlevel trough combined with high pressure over the eastern U.S. will allow Gulf moisture and higher dew points to stream into southern Wisconsin. The front will push through later in the week bringing somewhat cooler temperatures. Lighter precipitation may linger into Thursday or Friday.

AVIATION. (Issued 957 AM CDT Thu Apr 22 2021)
Expect VFR conditions to continue as high pressures builds to our south. Winds will mainly be from the west to southwest west with gusts nearing 15-20 kt this afternoon. Clouds begin to move in with the next system that will bring chances for showers to southern WI Friday morning and into the afternoon. Ceilings may drop to MVFR values Friday morning and into the afternoon.
RAH
MARINE. (Issued 312 AM CDT Thu Apr 22 2021)
Light westerly winds are expected to increase and shift more southerly this afternoon as high pressure builds across the Ohio River Valley. Could see gusts in our nearshores approach 20 knots at times this afternoon, but will hold off on the Small Craft Advisory. Winds will likely stay elevated tonight, but will shift more southwesterly. South to southwesterly winds continue into Friday as the surface high skirts eastward. Northerly winds are then expected to develop into the weekend as a low passes to the south of Lake Michigan. Could see gusts up to around 30 knots across the open waters Saturday night.
