.DISCUSSION...
Issued at 108 PM EST Thu Feb 12 2026
- Dry and warmer through the weekend
A large area of high pressure over the middle of the country will
move southeast to the Carolinas by the weekend. We`ll benefit from
the high pressure in the form of dry weather and sunshine through
the weekend.
A strong southern stream system will move east across the Deep
South late in the weekend spreading rain as far north as central
IN/OH. Concurrent with that, a northern stream low will move east
across Ontario and drag a cold front into northern Lower Monday.
However, that system will be too far north for any precipitation
over the cwa.
A slow warming trend is expected through the weekend as heights
aloft continue to rise. Highs Saturday in the lower 40s will edge
up into the mid 40s Sunday and Monday and upper 40s Tuesday.
- Rain, possibly followed by snow next week
The aforementioned cold front will slowly sink south across
northern Lower, but get hung up by south flow ahead of a Colorado
low moving east across the Plains late Tuesday. Warm
advection/isentropic lift will result in rain developing over the
cwa Tuesday evening and continuing into Wednesday. As the low
moves east along I-80, rain will lift northward Wednesday night
and gradually diminish Thursday, perhaps as some light snow as
colder air works south behind the low.
Another system behind that low will tap into some of the colder
air and generate some mixed precipitation Friday along with
potentially accumulating snow.
