* At 2:30 AM a large area of rain was moving east/northeast across North and East Texas. This area of rain extends back west to Abilene to near San Angelo. Additional precipitation is developing on the western edge of the precipitation shield in the Concho Valley and Big Country.
* A layer of warm air above freezing still exists about 4,000 feet above the ground. As the upper level low pressure moves into the area very cold air will quickly move in and cause precipitation to change over to snow. Surface temperatures will not react to the cooling temperatures above and should remain at or just above freezing. The changeover to snow is expected to occur sometime after 4 AM and could occur rather quickly across North Texas as the low moves in.
* We still expect a heavy wet snow to impact the morning rush hour in the D/FW Metroplex and in locations north and northeast of the D/FW Metroplex. Temperatures are at or just above freezing which means a widespread ice event si not expected. However because some wet snow will be heavy it could accumulate on bridges and overpasses, perhaps even some surface roads. Some of it will melt and turn into slush making for a slippery morning commute. Give yourself extra time if you’re heading into work/school and remember to mind those bridges.
* Snow amounts of 1 to 3 inches on grassy surfaces and perhaps elevated surfaces still seems likely this morning in D/FW and points north and northeast. Some locations could receive locally higher amounts of 4 to 5 inches. Keep in mind this snow will all fall in a relatively short period of time (3-6 hours) which means it could be heavy. Snow will exit the D/FW Metroplex to the east by 10-11 AM and exit East Texas by 2 PM. With surface temperatures above freezing widespread ice is not expected. However slush from the melting snow could be cause some slippery spots this morning and early afternoon. Snow should quickly melt as temperatures climb into the 40s and skies clear out this afternoon. The evening rush hour should be in decent shape.
