KEY MESSAGES
- Mild on Sunday and Monday into the 50s.
- Temperatures will again drop below normal for much of next week as a shot of cold air moves into the Midwest.
SHORT TERM /THROUGH SUNDAY/
Issued at 145 PM CST Sat Dec 7 2024
Clipper system in the northern Great Lakes region will continue to pull milder air into our forecast area through Sunday. Areas of high clouds are expected. Lows tonight mainly in the 30s, while highs on Sunday push into the mid to upper 50s.
LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/
Issued at 145 PM CST Sat Dec 7 2024
Sunday night: Deterministic models have shifted the storm system farther to the southeast, so have removed the mention of pops.
Monday: Another above normal day with highs in the upper 40s to lower 50s. This due to another Alberta Clipper moving across the northern tier of the country.
Monday night and Tuesday: Reality returns as the clipper tracks to the northern Great Lakes, sending a strong cold front sweeping across our area. Lows will bottom out in the lower to mid 20s with highs in the upper 20s to lower 30s.
Tuesday night through Thursday night: Quite cold again with highs only in the 20s and lows in the single digits and teens.
The ECMWF hints at the potential for some snow showers with steep lapse rates associated with a cold pocket/deep trough.
However, the GFS keeps the bulk of these snow showers to our north. Low confidence at this time for later shifts to monitor.
Moisture availability/forcing will be a concern.
Friday through Saturday: Roller-coaster ride with regard to temperatures as we warm up again as another clipper tracks to our north. Highs will be pushing into the 40s. Global models hint at the potential for precipitation during this time-frame but confidence is low this far out, with regard to timing and pcpn type.
AVIATION /00Z TAFS THROUGH 00Z MONDAY/
Issued at 950 PM CST Sat Dec 7 2024
LLWS between 1000 and 1500 ft was slow to develop this evening with speeds of 45 knots will continue through 08 UTC. VFR conditions are expected to continue through the period. Few to scattered clouds at 25kft are expected through the period. After 00 UTC on Sunday, mid level clouds will begin to spread into KMLI and KBRL as a storm system passes to our south and east. West winds tonight will turn to the south after 12 UTC on Sunday and continue through the remainder of the period. Gusts up to 20 knots are possible at KBRL and KMLI late afternoon into the evening hours.
