A Chilly Rain with a Mini-Winter Thaw

The Jetstream pattern this week is one I mentioned in last week’s blog. A strong storm system will eject across the Southern Plains and generate quite a bit of precipitation. The wild card was going to be if there was enough cold air nearby to work in from a glancing blow. The good news is that it’s been pushed off to the northeast, so instead of ice, it’ll just be a chilly rain.
The pattern this week shows the upper-level low moving in mid-week. The colors indicate lift in the atmosphere and a lot of it! The National map shows where the freezing line will be (in blue), so we’re in the clear.


As a matter of fact, this week most of the country will start a moderating trend as the cold stuff stays trapped in Canada.

When the precipitation starts Wednesday morning, temperatures will be close to freezing across the north and into the panhandle. I expect them to warm before raindrops hit the ground in N and NE OK, but there may be a touch of ice for the panhandle region. The rainfall lasts through Friday morning.


A conservative model blend estimate of rainfall is quite impressive!

When will the next round of snow or ice occur? There is a signal beyond this week around the middle of next week to the 7th, so stay tuned!

In the meantime, enjoy the slight warmup as we move through our week. Might be a good time to sneak in some outdoor work while it’s not so cold! -AT
