Rounds of rain are possible on Friday, with temperatures staying chilly all day long. Highs will only be in the 40s. While it not rain all day long or constantly, pretty much everyone will see rain at some point tomorrow.
Rain continues into Friday night, with the potential for heavier showers Friday night into first thing Saturday morning. Widespread flooding issues are not likely with this round of heavier rain, but some localized flooding of creeks, rivers, and low-lying areas is possible.
Highest coverage of rain will shift to the northern half of North Texas by Saturday afternoon. This will also be when colder air is moving into the area. A transition from rain to a wintry mix is possible across far western and northern North Texas (along the Red River) during the afternoon and evening. If this does occur, surface temps look too warm for any accumulation or to cause icy roadways.
Any precipitation moves out of the area Saturday night into Sunday leaving a cold but dry day on Sunday for any Dallas Marathon runners.
While widespread rain is likely, rain totals will vary across the area. Totals of 1-2 inches are possible across western North Texas, 2-3 inches for the DFW area, and 3-6 inches for eastern and southeastern North Texas. A Flood Watch is in effect along and south of areas from Canton to Athens to Corsicana. This area will likely see the highest rain totals and best chance for localized flooding issues.
