5/10 – Rob Knight’s “HOT PATTERN” Tuesday Morning Forecast
Hot and dry pattern continues as upper level high-pressure builds SW to NE across the Mississippi Valley. This will easily supports high temperatures around 90 degrees, with isolated locations approaching mid-90 with the heat index.
Low-pressure currently in the western Atlantic will approach the east coast of Florida by the end of this forecast period. At the same time, an upper level trough will be swinging northeast across the High Plains. As a result of both of those systems moving to those regions, the high-pressure will get squeezed north. Losing the subsidence from that high pressure will allow for some afternoon convection to start developing Thursday.
Moisture levels won’t be quite as high on Friday, so would expect lower rain chances then, probably isolated areal coverage. Scattered coverage for convection also looks to be on tap for Saturday and Sunday afternoons diminishing during the early evening. The additional rain chances and cloud cover should prevent high temperatures from getting much past 90, if even that warm, Friday through Sunday. As moisture shifts east of the area early next week, things will start to heat up again.
