UPDATE: 10:00 p.m.
The latest high-resolution model runs suggest the weekend rain system may pick up a little speed, which would focus the rain more on Friday and less so on Saturday.
However, I'm going to leave the percentages as is for Fri-Sat until I see what the morning output on Wednesday shows, this establishing better continuity.
Have a great night - Steve
Rain Potential Increases Fri-Sat
5 p.m. Tue 26 August 2014
A large upper high that has controlled our weather since the middle of last week will begin to weaken and move to the east over the next two days. While this is taking place, a well-defined mid-level trough will continue to slowly advance our way from the west. Low-level wind flow is turning more to the east as well. The net result of these changes is a gradual cooling trend followed by an increase in rain potential.
The western trough is a slow mover so I don’t expect any significant rainfall until Friday when it gets close enough to begin destabilizing the atmosphere. The continued slow movement of the system suggests rain potential will continue for Saturday.
While I don’t expect it to rain all of the time, there will be the potential for locally heavy precipitation and gusty winds with these storms. The trough should pass by Saturday night, and this should leave the second half of the Holiday weekend dry.
High pressure rebuilds next week and temperatures look to run above normal into the first few days of September.
Here are the numbers:
Tonight: Clear and Warm…..Lows 71 to 76
Wednesday: Mostly Sunny…..Highs 94 to 98
Thursday: Partly Cloudy …..72/95
Friday: 50% Thunderstorms…..75/92
Saturday: 50% Thunderstorms …..70/90
Sunday: Partly Cloudy …..71/94
Monday: Mostly Sunny …..75/96
Tuesday: Mostly Sunny…..75/96
May You Have a Super Wednesday!
