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 351 AM CDT Sat Jun 15 2024
