Cooler temps before front brings rain
From NWS: Scattered thunderstorms are expected along and ahead of a cold front early next week. High pressure ridging will continue to influence the forecast area to begin the extended period, which will lead to the continuation of benign and seasonal conditions. Cloud coverage will begin to increase on Saturday as the upper level ridge moves off to the east and is replaced by upper level southwesterly flow. More moisture is then expected in the area on Sunday due to return flow off the Gulf of Mexico, which will lead to an increase in PoPs, in the 20 to 30 percent range in the afternoon.
Medium-range models are then fairly consistent in regards to the passage of a cold frontal system through the forecast area early next week. Widespread heavy rain, with PoPs in the 60 to 80 percent range, and the potential for at least isolated strong to severe thunderstorms can be expected ahead of this front. It is most likely that these conditions will be observed on on Monday night and into Tuesday. Strong cold air advection associated with another shortwave, along with the cooler air already in place behind the passage of the front, could contribute to significantly below normal temperatures to the area in the later parts of the week.
