Updated aviation portion for 00Z TAF issuance

SHORT TERM. Tonight and Monday Issued at 236 PM CDT Sun Sep 19 2021

The main point of emphasis over the next 24 hours will be on precipitation chances mainly over eastern WI Monday morning and timing of main band of showers/storms headed toward central WI late Monday afternoon.

The 19Z MSAS surface analysis showed high pressure over the eastern Great Lakes, an area of low pressure just north of Lake Winnipeg and another low pressure over the northern Plains. A cold front connected the lows from southern Manitoba southwest through the northern Plains into the central High Plains. Visible satellite imagery indicated clear skies over northeast WI with cirrus clouds to the west and cumulus clouds to our south.

A mild night is in store across northeast WI as south-southeast winds at 5 to 10 mph at the surface and stronger southerly winds aloft pull warm/more moist air into the region. Look for min temperatures to be in the upper 50s to lower 60s north, lower to middle 60s south.

The quiet weather pattern comes to an end on Monday as a two- pronged precipitation event takes aim at northeast WI. First, a mid-level shortwave trough is forecast to lift northeast into the region by late Monday morning in sync with an influx of gulf moisture that will steadily increase through the day. This little system to bring a chance of showers/slight chance of thunderstorms mainly to eastern WI from late morning into mid-afternoon. The second precipitation event would approach central WI late in the afternoon as a cold front moves into western WI. Most of the models show showers/thunderstorms to be along the cold front, however cannot rule out some precipitation developing ahead of the boundary. Thus, will have increasing pops across central WI in the afternoon with the bulk of the locally heavy rain, marginal risk of severe storms holding off until Monday evening. Max temperatures for Monday to range from the middle 70s near Lake MI, middle 70s to around 80 degrees inland.

LONG TERM. Monday Night Through Sunday Issued at 236 PM CDT Sun Sep 19 2021

Models still not fully in agreement on precip chances leading into the cold front passage Monday night. NBM solution remained similar with timing of frontal precipitation and that solution is supported across the state starting at 00Z Tuesday. Thunderstorm activity looks to be mainly associated with the frontal band that moves through northeast WI between 00Z and 06Z. Some storms could be severe mainly based on wind threat.

Cooler and breezy conditions will surge into the area behind the front for Tuesday. A few spotty showers may linger over far north- central WI on Tuesday morning, but a gradual clearing is expected through the day. Temps on Tuesday will fall back into the 60s. Surface high pressure will build towards the region on Tuesday night, but the gradient may be just enough to prevent a frost threat. A few lows may fall into the upper 30s though.

Cooler weather is then forecast for the rest of the week. With the high directly over the region, Wednesday night still looks to have the highest potential for frost; after that, temperatures moderate. High temps Wednesday onward look to range mainly from the upper 50s to near 70 degrees.

AVIATION. for 00Z TAF Issuance Issued at 709 PM CDT Sun Sep 19 2021

VFR conditions are expected overnight, however strong winds just above the surface will keep the mention of LLWS in the central and north-central WI TAF sites through mid-morning Monday. Southerly surface winds will increase Monday afternoon with gusts up to 25 kts.

MVFR cigs are expected to lift from south to north late Monday morning as a surge of Gulf moisture moves into the area. There is potential for light showers to accompany this moisture across the east-central WI TAF sites, and possibly some thunderstorms. Confidence is not high enough at this time to include thunderstorms in the TAFs since coverage will be isolated. Towards the end of this TAF period, a cold front will be nearing/arriving at the central and north-central WI TAF sites, and provide the next chance for showers/slight chance of thunderstorms. Timing is not exact at this time, but anticipate clearer timing in later issuances.
