A large upper-level low will develop over the next 24 hours in the midwest. It will bring cold air and stormy weather to many states north of Alabama, as it moves very slowly eastward. When upper altitude lows get cut off from the main flow like this, it is hard for them to move much, and they are tough to forecast.
Right now, it looks like an upper-level disturbance will rotate around the low to its south and bring a cold front through Alabama tonight. We'll get some rain, and maybe some thunder, but we do not expect any severe weather since dewpoints will remain low. After that, we should see highs only near 70 Thursday and Friday with gusty winds. The low may push one more shot of cool air in here Saturday, with lows dropping into the lower 40s in north Alabama and highs on Saturday feeling like autumn...in the 60s.
