A strong cold front pushed into North Texas Monday afternoon. Strong north winds brought some clouds that will continue until early Tuesday morning.
Temperatures will drop into the upper 20s early Tuesday morning with a hard freeze overnight. Highs will climb into the 40s by afternoon. Gradual improvement can be expected the rest of the work and school week with chilly mornings and temperatures in the 50s during the day. Showers will be possible Friday and Saturday. Temperatures by the weekend should be back into the 60s.
Overall, we’re only expecting a glancing blow of the Arctic air. Up north in the Midwest and Great Lakes, temperatures will be dangerously cold. For example, by Wednesday and Thursday morning, Chicago is expecting low temperatures around 20 degrees below zero. And that's the air temperature! Wind chill values could easily be 40 to 50 degrees below zero for parts of Minnesota, Wisconsin, Iowa, and northern Illinois.
