7/6 – The Chief’s “Hotter Temperatures Ahead” Wednesday Morning Forecast

At the surface, high pressure is centered pretty much over our area as the disturbance that brought the heavy rainfall to portions of the area yesterday, continues to drift westward toward the Sabine River.

High pressure at the surface and aloft will basically sit in place over the next 3 days. Unfortunately, the very moist airmass isn’t going anywhere, either. While we don’t have yesterday’s disturbance to enhance lift across the area, differential heating should be more than enough to trigger t-Storms  by late morning/early afternoon each day. Initiation will be closer to noon in most areas today, then early afternoon tomorrow and Friday. With the slight drying of the airmass over the next couple of days, anticipate a gradual decrease in areal coverage tomorrow and Friday. Isolated spots of very heavy rainfall can be expected with these storms

An upper disturbance will try to force a frontal boundary into the area Sunday or Monday. That’s somewhat unusual for July around here. It now appears that most of the area won’t really get into a drier airmass, so there will be a continuing threat of daily, diurnally enhanced t-storms.
