white-christmas-watch.wav Updating the post from earlier. The 500 mb disturbance is approaching from the west, and mid-level clouds are already over much of Alabama now. Temps currently 35-38 in most areas, but should not drop much more with thickening clouds … Continue reading →

white-christmas-watch.wav Only the 00 UTC NAM is in yet…but the trend has continued toward bringing the precip farther west into Alabama tomorrow! We’ll have to wait and see if the GFS, UKMET, and Canadian are in agreement, but the NAM … Continue reading →
