A complicated set of factors coming together in the atmosphere over North Texas to produce some snow for Christmas afternoon and evening. We’re watching an upper level low pressure centered over the Four Corners this afternoon. It should swoop across North Texas by tomorrow to give us a chance of snow.
***IF THE PATH OF THIS LOW IS OFF BY EVEN 40-50 MILES, IT WILL HAVE MAJOR IMPLICATIONS ON THE SNOWFALL FORECASTS – FARTHER NORTH = LESS SNOW FOR NORTH TEXAS; FARTHER SOUTH = MORE SNOW FOR NORTH TEXAS***
We will start off with rain developing in North Texas overnight tonight into early Christmas morning – hopefully Santa has a raincoat if he’s flying after midnight. Dynamics in the atmosphere will lend themselves to a chance of strong to severe storms in southeastern portions of North Texas tomorrow morning. We could have strong winds, hail and even isolated tornadoes…but we think the best chance of that will be in SE Texas and Louisiana.
By midday, cold winds will be blowing in, dropping temperatures into the 30s from the north. Rain will begin to changeover to snow in our western counties.
The change to snow will occur in the DFW area shortly after noon or 1pm on Christmas…it will be blowing snow with very strong northwest winds up to 40 mph! Snow should be fairly light along the I-20 corridor with moderate snow along the Red River. IT WILL BE VERY VERY COLD STARTING TOMORROW AFTERNOON WITH WIND CHILLS BETWEEN 10° AND 20°!!
Snow will end from west to east after sunset and should be tapering off by 10pm tomorrow night.
So how much snow are we talking? Again, this is the forecast as of Monday afternoon…this could change dramatically depending on the exact track of the low. So keep checking in. Could see up to 1″ of snow in the Metroplex with higher amounts the closer to the Red River you live. More than likely, the heaviest snowfall will be along the Red River in Northeast Texas.
Oklahoma will see the worst of the weather tomorrow into Wednesday. Very dangerous travel there, where 4 to 8″ of snow is possible in eastern Oklahoma thru tomorrow night. Winter storm warnings are up for them.
So here’s the bottom line for Christmas Day in North Texas. Starting with rain and storms…ending with snow.
In terms of travel, the ground will be wet in the morning…but just wet. As snow begins to fall, the ground should stay mainly just wet. The blowing snow will reduce visibility tomorrow afternoon…so be careful if you have to drive around. As temperatures drop into the 20s after sundown tomorrow, expect a few icy patches to start forming…first on bridges and overpasses. The snow should end by 10p Tuesday, but any residual moisture on the roads will have a chance to freeze Tuesday night into Wednesday morning. The Wednesday morning commute could be difficult, especially on bridges and overpasses.
It will be a cold week in North Texas. Expect temperatures near 20° in the Metroplex by Wednesday morning…we will just barely get above freezing Wednesday afternoon, but most of our icy spots should be gone by then.
