12/3 – Rob’s “Warm & Humid” 1st Weekend of December Forecast
High pressure really doesn’t give way over the next 24 hours as an upper-level disturbance will move from Texas across the area Saturday morning. There’s essentially no moisture for this system to work with, and don’t expect to see any more than very isolated showers occurring with this system. What this system does accomplish, though, is to shift the surface high pressure eastward. Moisture will gradually increase Sunday and Sunday night with southeasterly winds. The timing of the approach of the cold front from the northwest has slowed over the last 24 hours. Any precipitation on Sunday should remain rather isolated, and even Sunday night, may only occur very late at night across northwest sections of the area. Above normal temperatures continue through the weekend, with readings 10 degrees or more above normal.
There appears to be at least a brief window for t-storms over portions of the area as stability is expected to decrease. The front pushes through the area but returns north as a warm front. Rain chances quickly rise once again on Tuesday with a warm front moving through the area in advance of yet another disturbance trough approaching from the west. This keeps rain chances in the 30-60% range from Tuesday afternoon all the way through the day on Thursday. Models are hinting at the potential for strong to severe storms, although it looks like the best threat will be to our north.
