James Spann forecasts more cool, dry days for Alabama from Alabama NewsCenter on Vimeo.
DRY AIR STAYS IN PLACE: Temperatures were mostly between 28 and 34 degrees across Alabama early this morning with a clear sky. The sky will stay sunny today with a high in the low 50s; the average high for Birmingham on Jan. 11 is 54. Dry weather continues through Friday with seasonal temperatures. A few clouds will show up Thursday as an upper trough moves through. Expect highs in the 50s and lows in the 30s.
THE ALABAMA WEEKEND: Clouds return to the state Saturday ahead of a disturbance that will bring rain back to the state. Models have trended a bit slower, suggesting now the main chance of rain will come Saturday night into Sunday morning. Moisture will be limited, and rain amounts should be less than one-half inch. There most likely won’t be any thunder with basically no surface-based instability.
Thermal fields suggest potential for a few snow flakes with this feature over the Tennessee Valley of far north Alabama Saturday night, and possibly on the back side of the departing system Sunday morning down to I-20. Probabilistic outlooks from global ensembles, however, for now show only a low chance of any accumulation or impact. As always, watch for forecast changes as we get closer to the weekend.The highs Saturday will be in the 50s. Sunday will be colder, with highs in the 40s.
NEXT WEEK: The weather will be cold and dry Monday; after a low in the 20s, the high will be in the mid to upper 40s. Temperatures return to the 50s Tuesday and Wednesday, and rain will likely return Thursday.
