7/6 – Rob Knight’s “Lower Rain Chances, Hotter Temperatures” Afternoon Forecast

High pressure is centered pretty much over our area as the disturbance that brought the heavy rainfall to portions of the area yesterday, is well to the west. 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 has already begun but will become a bit later tomorrow and Friday afternoons. 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.

High pressure will continue to shape the forecast this weekend as temps will continue to max out in the low 90s. With low level moisture still in place, HEAT INDICES will max out between 100-107 degrees. While enjoying the weekend outdoors, remember summertime safety tips as hydration, taking periodic breaks and keeping an eye on each other.

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.
