DISCUSSION
Issued at 216 PM EST Tue Feb 20 2024

- Above Normal Temperatures and a Chance for Rain

Temperatures have warmed into the mid 40s to low 50s this afternoon with areas toward Mount Pleasant in the low 40s.
Tonight temperatures drop into the 30s with some cloud cover moving in for this evening.

The low level jet and warm air advection move in overnight into Wednesday with 925 mb temperatures ranging from 4 to 8 C across the area. This will result in temperatures several degrees warmer than today with highs in the mid 40s to upper 50s from north to south. Along with the warm air advection moisture will be increasing over the area with the help of some positive vorticity advection aloft. At this time precipitation looks to hold off for the area until Wednesday night. A low pressure system will move through the southern portion of Michigan's Lower Peninsula bringing with it scattered showers. The best chances are along and south of a South Haven to Lansing line (50 to 60 percent) with lower chances to the north. Those north of this line could stay dry as the better lift with the trough axis is focused more over southeast Michigan. Rainfall amounts are expected to remain under a half inch. Temperatures Wednesday night into Thursday will remain on the warm side with lows in the 30s to low 40s and highs before the front moves through Thursday in the upper 40s to low 50s.

- Brief Cold Period with Snow Possible Late Friday into Saturday

A long wave extended trough will swing through Michigan Friday into Saturday. Ensembles continue to show anomalously cold temperatures through this period. Current ensembles from NAEFS and EC showing -10 to -14 at 850 hPa. The best moisture however is ahead of the front and should be to the southeast. So the moisture staved region behind the front should only have light snow showers. Positively tilted ridge through the mid-levels will coincide strong mid to upper level flow that will drop cold temperatures through the region bringing temperatures for Michigan back to normal and allow for cold weekend. Strong westerly flow should continue through Sunday. So continued cold air advection along with strong winds should make Sunday quite blustery.

- Warm Up Expected Next Week

A large upper level low over Canada will dominate the mid range and should allow for warm air advection and southerly winds early next week. This will force temperatures back to well above normal. There continues to be a signal for precipitation by late Monday through mid next week. There does remain a chance for some instability towards the end of the month.

AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/
Issued at 1256 PM EST Tue Feb 20 2024

VFR conditions are expected with some broken high clouds expected to move through this evening. Low level wind shear will be possible tonight as the inversion builds in with light winds at the surface and winds up to 40 knots around 2000 feet above ground. A broken cloud deck moves back in for Wednesday morning with ceilings around 7000 feet for MKG and around 16000 feet for the rest of the TAF sites.

MARINE
Issued at 216 PM EST Tue Feb 20 2024

Southerly winds pick up this evening with gusts up to 25 knots and waves around 4 feet. Winds drop below small craft levels Wednesday but waves around 4 feet could linger. Next chance for hazardous conditions will be Friday with gusty northwest winds and building waves.
