The broad dome of high pressure that is expected to bring very hot temperatures to the region is also forecast to weaken and back southwest into Mexico.
As the high shifts southwest, it is expected to cause winds in the middle and upper atmosphere to flow from the southern Rockies into Texas for most of this week.
This type of pattern in early June often results in a very active weather pat- tern for much of Texas. In this pattern, waves of low pressure often move in from the northwest, causing the development of widespread rain showers and thunderstorms.
Forecasts call for a weak cold front to sink south into Central Texas the middle of the week and this feature may help to enhance the chance for rain and thunderstorms.
The outlook for this week shows a high chance for rain through Thursday, with the chance for rain decreasing late week into the weekend.
The National Weather Service’s rainfall forecast through 7 p.m. Friday calls for widespread totals of 2-4 inches, with some pockets of 3-5 inch totals possible.
May Rainfall
The month of May concluded with rain totals above normal at most locations.
Some of the highest totals for the month occurred around Lake Buchanan, where an LCRA gauge on the northeast side of the lake recorded 10.5 inches.
A gauge located in western Fayette County recorded a monthly total of 9.34 inches.
The area receiving the least amount of rain was across the western Hill Country between Eldorado and Sonora, extending east to near Harper, where monthly totals only averaged between 1 and 2 inches.
