7/26 – Rob Martin’s “Stagnant Pattern” Tuesday Evening Forecast

More sunshine today bumped to those real-feel temperatures above 100 again. The diurnally-driven storms will continue each day, primarily driven by sea-breezes that converge with flows over land, creating lift in the atmosphere. Moisture continues to stay very elevated so expecting a similar pattern today where storms that do form would be extremely efficient rain producers with high rainfall rates with slow storm movement.

High temperatures for places that don’t get any rain cooling is expected to be in the low 90s and heat index values in the 100s. Not anticipating an issuance of a heat advisory but it may get close in a few spots especially in the urban areas if they don’t get any relief from rain. Rain chances will increase a bit toward Friday before backing off some for the weekend.

 High pressure that had been the dominating pattern will finally begin to shift eastward and weaken starting around the weekend. This is mainly reflected as higher rain chances in the Friday to Sunday period. Starting around Sunday the high pressure will start to build back westward so that will knock down the rain potential again with the increased subsidence.

Otherwise not too much change and temperatures should remain around the average for this time of year.
