KEY MESSAGES
- Next round of showers and storms expected for Thu and Thu evening. Otherwise a warming trend into the weekend with just small chances of rain.
SHORT TERM
Issued 346 AM CDT Wed May 15 2024
Today through Friday night:
Scattered stratus over far srn WI will dissipate later this morning as low pressure weakens as it moves ewd across the Ohio Valley, and nly winds bring drier air into the region.
Otherwise the sfc ridge will remain over WI today before shifting ewd tnt. Temps will return to the upper 60s to lower 70s well inland with near 60 at the lake front.
A weak sfc low and upper level trough will move from MN to wrn Lake Superior on Thu. PWs will increase to 1-1.2 inches with very marginal instability, but increasingly moist soundings. The HRRR and GFS/ECMWF support likely PoPs from west to east through the day as the trough passage extends south into the area. Scattered showers to then linger into Thu nt with the weakening sfc trough passage over the area and another weak shortwave trough approaching from the west. The trough will pass early Fri AM but isold showers could linger in far ern or srn WI. Some uncertainty on timing of drying for Fri which will impact cloud cover and temps. At this time counting on some sunshine with temps ranging from the 60s near the lake to middle to upper 70s over south central WI. Shortwave ridging and a dry fcst for Fri nt.

LONG TERM
Issued 346 AM CDT Wed May 15 2024
Saturday through Tuesday:
Ridging nudging northward into the Upper Mississippi Valley and steady southerly winds at the surface may lead to widespread temperatures over 80 degrees on Saturday. Modeling has come into agreement that the interplay between an Ohio Valley low and a 500 mb shortwave driven low in Canada and the northern Plains will drape a cold frontal feature through Wisconsin Saturday evening, although better forcing remains across northern Wisconsin and the UP of Michigan as upper level ridging steers the northern low into northern Canada. In addition, this upper level ridging brings in warmer air aloft and prevents instability development during the day. Therefore, kept the NBM 15 to 30 percent PoPs for this timeframe.
High pressure remains prominent through Saturday night into Sunday, with an additional shortwave propagating eastward from the Colorado Rockies Sunday night into Monday and a developing low in the lee of the Canadian Rockies creating a baroclinic zone in the Upper Midwest. Plenty of uncertainty remains in exact timing and intensity of precipitation across southern Wisconsin from Sunday onward as triggers for convection transition to a shortwave-driven pattern beneath general ridging. Because of uncertainty, left NBM PoPs alone. However, there will likely be periods of dry conditions Sunday into Monday.
Intrusion from the tropical jet stream into the central Plains midweek may result in enhanced cyclogenesis and therefore better chances for widespread precipitation Tuesday into Wednesday.
