Issued 1025 AM CDT Sat Jun 15 2024

With the ridge now over the region we have dried out quite a bit, especially in the low to mid levels. There has been some embedded shortwave activity aloft that is associated with good moisture gradually sliding in this morning, however the low level dry air has largely prevented any precip from reach the ground. We cant rule out a few sprinkles in our far west but it remains likely (80%) to be virga.

As the system pushes in through the day and particularly into the evening we will gradually moisten up in the low levels, though primarily further west. It will likely (80%) remain drier further east. The upper level shortwave will continue through the region into the evening and overnight but the difference will be the LLJ jet building into the region which will enhance forcing in the mid levels. The issue with this is the LLJ will largely be setting up further west. Given the drier air further east it could set up a fairly stark boundary for dry and wet. There is some storm potential with this given the LLJ and enhanced shear (30-40kts) that it will provide but given the timing the instability will be rather low so any storms are largely expected to be weak. The best chances (80-90%) for precip/storms from this system will be further northwest though the entire northwest half of the CWA will see chances (60-90%)
with the southeast more likely (60-80%) to remain dry.

This system will slide out by Sunday morning with the rest of Sunday looking dry. Late Sunday night into Monday morning we should expect the LLJ to ramp up again, though weaker in our region. The LLJ will increase in strength into the day Monday with general shower/thunderstorm chances (30%) expected.

Today and Tonight:

High pressure over Ontario will bring light southeast winds. Cirrus associated with convection over the plains will continue to spread into southern Wisconsin. Showers over Minnesota and Iowa associated with a weak shortwave within mid level ridging should dissipate as they move into southern Wisconsin an encounter drier air.

There is a 20% chance for thunderstorms this evening north and west of Madison as a deeper shortwave approaches the region. Storm chances expand across southern Wisconsin overnight as the shortwave moves through and increase to over 75% north and west of Madison.
Areas south and east of Madison may stay dry. A 40 knot low level jet will shift into western Wisconsin during this time bringing a surge of moisture. Some storms may be on the strong side as instability builds to 1500 MU CAPE early Sunday morning with 20 to 30 knots of shear.


Issued 351 AM CDT Sat Jun 15 2024

Sunday through Tuesday

Some showers may linger into Sunday morning before ridging builds back in. Can't rule out a thunderstorm during the afternoon, which the HRRR shows, but we are capped around 850 mb. Much warmer and more humid temperatures are expected for the early part of next week. A strong mid level ridge sets up over the southeast U.S.
bringing as low pressure develops over the central plains. This brings strong and moist southerly flow into the region. Highs will be around 90 with heat index values in the 90s. Some areas may see values near 100 on Monday.

There is a 30% chance of storms on Monday and Tuesday. Many areas will be dry. The better chances will be to our northwest where a strong low level jet surges into a frontal boundary draped across Minnesota into northern Wisconsin.

Wednesday through Friday

Warm temperatures will continue but likely will not be as warm as earlier in the week. The frontal boundary will push southward through the state sometime early in the period bringing a better chance for rain and thunderstorms.


Issued 1025 AM CDT Sat Jun 15 2024

VFR conditions are expected through the TAF period. However, while much of the day is expected to remain quiet as we head in the late evening and overnight period we will see chance for showers and maybe even a few weak storms. Most of this is expected to remain off toward west central WI. There remains a decent chance (50%) for a shower or storm closer to Madison but the better chance will remain north and west. Thus there remains a slight chance (20%) for a period of MVFR VSBYS. Otherwise MVFR CIGS will likely (80%) remain off to the north and west of southern WI. Scattered CIGS expected across most of southeast WI during this period. System will push out Sunday morning.
Otherwise expect southerly winds gradually increasing overnight into Sunday, turning more SSW and persisting through much of the day.


Issued 351 AM CDT Sat Jun 15 2024
