DISCUSSION

Short Term
Today
Tonight...and Saturday

Jet energy moving through the southwest upper flow will induce rising motion over a warm front that was over northern Illinois early this morning.

There are two or three discernible jets that will move across the region this afternoon and tonight. The first one will produce overrunning showers and thunderstorms that will arrive in central and northcentral Wisconsin by afternoon and in the east by evening.
the activity will continue tonight. An inch or two of rain is possible, especially north of highway 8. Some Urban and small stream flooding is possible the severe threat looks to be rather low, as the storms are not surface based and the air aloft is warm.

Cool outflow from the storms this afternoon and tonight will likely keep the warm front south of the forecast area through much of Saturday, though the ECMWF and Canadian bring it into the Fox Valley during the afternoon. Another jet streak will move across the area Saturday, and produce additional showers and storms. In addition to additional heavy rain, there could be some severe storms along and just north of the warm front. Damaging winds look to be the main threat, though a tornado cannot be ruled out.

Long Term...Saturday Night Through Thursday

Persistent high pressure over the southern US keeps an active sub- tropical jet running across the northern CONUS. There will be several chances for rain and thunderstorms through the extended period as multiple short-waves cross the region. At this point the flooding concern through the long term is rather broad brush, but will become more focused to areas that see the greatest rainfall amounts Friday and Saturday.

Saturday night through Sunday...Areas of heavy rain and scattered strong to possibly severe thunderstorms are likely to be ongoing into Saturday night as a cold front sweeps across the region and a low pressure system starts to depart to the east. Strong wind gusts are expected to be the main hazard with any thunderstorms by this time period. The axis of heaviest rain by this time will likely have shifted to east-central WI. By the time the rain is all said and done much of the region will likely be looking at 1.5-2.5 inches of rain, with locally higher amounts where the strongest convection ends up.

A short-wave following behind the main departing system is progged to dig south over northern WI Sunday returning a chance for showers and a few thunderstorms. With colder air moving in aloft low-level lapse rates are forecast to steepen Sunday which along with decent elevated instability and strong effect shear could sustain a few stronger thunderstorms, mainly for northeast WI where ascent is expected to be maximized.

Monday through Tuesday...Ensemble guidances is in decent agreement with a brief mover over the area Monday keeping much of the day dry. Temperatures and humidity will be on the rise Monday as return flow develops during the afternoon. The next period worth watching for possibly strong thunderstorm is Monday night into Tuesday morning across north and northeast WI as a low-level jet develops ahead of an approaching short-wave. Forecast sounds do show strong elevated instability and deep-layer during this period, however, a fairly strong cap is expected to develop during the overnight hour limiting the window for any convection.
If any storms do develop strong winds, hail and heavy rain would be the main hazards.

Rest of the Extended...With a ridge building over the northern Rockies during the middle part of next week the region will reside in northwest flow regime bring cooler temperatures back to the region. The northwest flow may also bring a drier air mass to the region which would limit the precipitation chances middle to end of next week.

AVIATION
for 18Z TAF Issuance Issued at 1158 AM CDT Fri Jun 21 2024

Periods of showers and thunderstorms are expected during the TAF period as a warm front slowly lifts north from northern Illinois.
After this first round of thunderstorms moves through early this afternoon, additional thunderstorm timing is problematic as CAMs models each have a different solution. Most of the models seems to be honing in on additional thunderstorms moving in later this afternoon and again sometime Saturday morning. Conditions are expected to fall to MVFR and eventually IFR as low level moisture and showers increase across the region. Significant rain is possible at times, with moderate to heavy showers.

GRB WATCHES/WARNINGS/ADVISORIES
None.
