DISCUSSION

Issued at 950 PM CST Sat Feb 21 2026

A weak shortwave trough is diving south behind the developing Nor'easter off the East Coast. This system is maintaining cold air advection over the region and keeping temperatures very cold. Temperatures fall into the single digits with wind chills as low as 5 to 15 degrees below zero. Surface high pressure moves in during the afternoon on Sunday, but the cold remains. Temperatures remain in the 20s. Temperatures plummet with snow covered ground and clear skies Sunday night. Temperatures bottom out as low as the negative single digits with wind chills 5 to 15 degrees below zero once again. As the surface high moves off to the east, southerly winds return to the area. This will be too late in the day on Monday to offer much warming. Afternoon temperatures continue to be cold in the 20s and 30s.

Tuesday marks the beginning of steady warming trend across the region. Increasing heights and southwesterly surface winds quickly warm temperatures. 50s and 60s are expected for areas without remaining snow cover, while snow covered ground keeps temperatures in the 40s. A mid-week system brings our next chance for precipitation. Temperatures hold steady in the 40s and 50s ahead of this system. An area of low pressure and a cold front swing through the area Wednesday evening into Thursday morning. This timing brings a chance of not only rain, but perhaps some snow as temperatures fall below freezing overnight. At this time, the chance of precipitation is low (20-40%). Despite this system, temperatures hold steady before increasing again on Friday. The warming trend is forecast to end by next weekend as the next weather system enters the picture. Cooler temperatures and perhaps a low (10-20%) chance of precipitation returns to the forecast.
