First, to those of you who put up your pole this morning:
Quick Summary: Next 48 Hours
Temps, feeling pretty good until Wednesday, when a cold front comes and cools us off.
Rain. A lot of it.
Tonight – Rain Blob Gone, Waiting for the Cold Front.
At 820 PM tonight, there were three things going on.
1. The rain blob was finally clearing us (notice the squall line that produced likely tornado damage in LA and MS today pushing into GA and south AL).
2. The cold front was approaching us, pushing a lighter, secondary blast of rain our way.
3. The cold front itself was sitting in MO, AR, and OK, inching its way toward us.
The HRRR model thinks the secondary blast of rain will deliver us light showers and falling temps Wednesday morning.
Wednesday – Showers & Getting Colder – Wake Up 52°, Falling Into the 40°s
Wednesday afternoon, most of the light rain should have ended. Temps will fall into the 40°s on the back of the west wind (the cold front).
During the evening, the models think there will be very little moisture leftover. Santa’s beard will freeze considering temps at 5,000 feet will be -6°C or so, but when he lands on your roof, temps will be well above freezing, so we don’t expect him to skid off the side and crush your fence. Leave him hot chocolate, though. -6°C is 21.2°F.
Christmas Day – Cool & Sunny – Wake Up 37°, High 46°
High pressure will build in and give us sunny skies and cooler temps. It’ll be chilly, so bring in your pets, and let them partake.
