KEY MESSAGES

- Elevated fire weather conditions today.

- Above normal temps expected to continue into early next week.

- Keeping an eye on severe thunderstorm potential next Tuesday.

SHORT TERM
Issued 325 AM CDT Sun Apr 14 2024

Today through Monday:

Early this morning we will see the surface low push out with higher pressure starting to fill in behind it with winds turning back to the northwest. The associated front will not feature much of a temperature change but will bring the wind shift and a much drier air mass. The temperatures today will likely (80%)
push the mid to upper 70s with some areas possibly reaching around 80, especially if we mix well enough. 925mb temps will reach the upper teens (degrees C) and with dewpoints expected to fall to near mid 30s (degrees F) by the late afternoon with strong mixing as high as 725mb (8000 ft). This will be a very dry day with RHs falling to 20-25% with potential (30%) for RHs to fall as low as 15%. Winds will be modest from the northwest with gusts as high as 20 mph as mixing should not tap into much higher winds aloft. This will make for elevated fire weather concerns today.

Into the day Monday, higher pressure will begin exiting the region with strong low pressure developing out west. This will bring light easterly winds to much of southern WI, though flow may be light and variable. While still being largely clear through the day 925mb temps (11-15 C) will be lower which will mean temperatures will not have the same upward potential with highs more likely (80%) to be in the upper 60s to mid 70s. In addition the easterly flow or at the very least the weak flow overall should allow for a lake breeze to kick in in the afternoon, perhaps impacting much of the eastern part of the CWA by the evening. The air mass will remain fairly dry though the lower temps and light winds will lessen fire weather concerns.

LONG TERM
Issued 325 AM CDT Sun Apr 14 2024

Monday night through Saturday:

The system expected to push through the Central Plains has slowed down a bit, likely due in part to the upper level closed nature of the low. This has delayed the onset for rain for WI.
Initially we were expecting to see some rain overnight Monday into Tuesday but now it appears as though we will not see rain until Tuesday morning at the earliest. This rain will be associated with the approaching warm front from the south and may have a few thunderstorms embedded. There will be plenty of other forcing mechanism at play as well including the upper level PVA, LLJ and WAA. Overall much of Tuesday is expected (80+%) to be rainy with lessening chances (20%) for severe storms in the afternoon/evening primarily due to later timing of the system, uncertainty in how far north the warm front with get, and how much instability could we muster up behind the warm front if it does lift north in time. In addition the lake could hinder some convection as well. We will continue to monitor the situation as the deep layer shear is enough to be concerned but the chances have certainly come down given the various concerns.

Given the slow moving nature of the closed upper low this will lead to a very slow progression of the system with the surface low gradually expected to push across the area Wednesday leading to another rainy day overall with some thunder chances (20%) as well, though no severe storms are expected. By Thursday this system will have pushed to the east for the most part, though a tongue of mid level moisture associated with some upper level PVA could impact the region Thursday but the moisture tongue at the 700mb level appears likely to miss the region largely to the south so will chances persist they are on the lower side due to the lack of ideal location at this time. While models are largely in agreement here we may see quite a bit change following the bigger system coming through Tue/Wed.

A cooler air mass will gradually push in for the weekend with higher pressure building. However, at this time the period looks largely dry with no major precip chances at this time.

AVIATION
Issued 325 AM CDT Sun Apr 14 2024

Breezy southwest winds currently across eastern parts of Wisconsin, which will only last to about daybreak before the front comes through with winds turning more northwesterly behind the front. Until that happens expect LLWS to be the primary aviation concern as west to southwest shear of 45-55 knots at around 2 kft is expected through around 12z (around the timing of the frontal passage). Into the day today expect northwest winds get slightly breezy in the afternoon with gusts up to 20 kts though largely lighter winds are more favorable (60%). VFR Conditions are expected through the remainder of the TAF period with largely light and variable winds overnight into Monday.
Winds will turn easterly later Monday with a lake breeze likely (70%) by the mid afternoon.

MARINE
Issued 325 AM CDT Sun Apr 14 2024

A surface high will push in today leading to largely quiet weather. Winds will shift this morning with the passing surface low, then mostly prevail from the northwest to north today.
However, the breezy southwest winds ahead of the front will keep the Small Craft Advisory in effect until 7am this morning.
Winds will largely be light and variable winds tonight into Monday. No precipitation is expected beyond this morning.

Gusty southerly winds are expected to return by Tuesday over the open waters with gales becoming more likely Tuesday into Wednesday. Some thunderstorms are possible across largely the southern portion of the lake during this period.

FIRE WEATHER
(Issued 325 AM CDT Sun Apr 14 2024)

Elevated fire weather conditions are expected today. Winds will switch to the northwest by mid morning and gusts this afternoon will be up to 15 mph with gusts up to 22 mph. Mixing heights will increase up to 6000 feet by mid afternoon, but winds aloft will be decreasing to 20 mph or less. Dry air in the low levels is anticipated with dewpoints dropping into the upper 30s. With forecast high temperatures in the upper 70s, the minimum RH values will be around 25 percent. The FFMC fuel moisture values are forecast to be around 90 to 91 for south central WI, with the highest values concentrated toward central WI where drought conditions persist. We issued an SPS in collaboration with neighboring offices and included areas where the fuels were driest since weather conditions are right at that marginal threshold for elevated levels.
