- Showers and thunderstorms into Friday
An upper level wave in the Upper Plains will track into the Western Great Lakes tonight. It takes on a negative tilt as it does. At the same time a low level jet will be tracking northeastward through Western Lower MI, generating lower level lift. Elevated instability will be present and PWAT values climb to well above normal levels at around 1.5 inches. Given the moisture, deep lift and presence of instability, showers and thunderstorms will become numerous tonight. High res models suggest several pockets of higher wind gusts could evolve overnight, but most indications are that they may struggle to reach severe criteria. The latest HRRR indicates the storms developing around Chicago will build northeast and into our CWA later this afternoon and into the evening. We did increase POPs accordingly.
On Friday the front will be pushing eastward through the CWA by mid afternoon. Thus any shower/storm activity will decrease from west to east through the early to mid afternoon hours. At this time the instability is progged to be limited so severe weather is not anticipated.
- Mild with several chances for showers/storms
A persistent long wave trough over the Rockies will send a steady stream of short waves toward the Great Lakes through the period.
Southwest winds aloft will also ensure that warm air flows across the cwa. Highs will be in the 70s throughout the period and nudge up to the 80 degree mark over the southwestern cwa Tuesday and Wednesday.
Saturday will probably be dry. However, a short wave moving across the region may give us some showers and perhaps a storm Saturday night.
Sunday looks dry, then another stronger wave arrives Monday night.
Strong low pressure over the northern plains is progd to push a warm front north into the cwa late Monday night. We'll likely see showers and storms develop along/ahead of the warm front with more development ahead of the trailing occluded front Tuesday.
Showers are possible again Thursday as the Plains low finally moves over the state.
AVIATION /00Z TAFS THROUGH 00Z SATURDAY/
Issued at 754 PM EDT Thu May 2 2024
A stationary boundary is located off to the south of the TAF sites this evening situated along the MI/IN line. Showers and a few thunderstorms have been drifting to the north, over Lower Michigan with a few embedded thunderstorms. At this point we feel thunderstorm coverage will be on the low side as instability is forecast to remain fairly low. The stationary boundary will lift north tonight though and continue to produce rain showers. A cold front approaches from the west late tonight and will bring in lower ceilings. MVFR and IFR ceilings will spread into all of the TAF sites from west to east from 07z to 14z. It will take a good portion of Friday to clear these lower clouds out. By 21z on Friday ceilings should have returned to VFR at the last place to lift which will be JXN. South winds tonight will shift to the west and northwest on Friday.
MARINE
Issued at 304 PM EDT Thu May 2 2024
With a low level jet track through the zones tonight the winds will be on the increase. They are currently progged to remain below criteria for small craft advisory so no headlines will be issued at this time. Outside of the winds increasing over the lake, gusty winds will accompany the showers and thunderstorms that track through Lower MI tonight.
