In a setup that has stark similarities to last weekend, an upper level low pressure will cause a surface coastal low pressure to develop on Friday. The process will trigger STRONG upward motion in the atmosphere over our region, and periods of moderate to heavy rain are possible beginning Thursday night, and lasting into early Saturday morning.
– 5pm to 10pm Thursday : patchy showers & drizzle develop
– 10pm Thu to 6am Friday : areas of rain develop
– 6am Fri to 6am Sat : Periods of rain likely, heavy at times
– 6am Sat to 12pm Sat : Rain tapers to drizzle
There are currently no flood watches, but latest guidance suggests that flood watches will be issued today. Very much like last weekend, this will be a challenging forecast with sharp cutoffs in moisture. One location could get 3″ of rain, and 30 minutes away an less than an inch falls. We will be tracking things closely… but expect a possible washout for your Friday outdoor plans. Some guidance has the heaviest rain to our east… let’s hope that becomes a trend on ALL of the guidance. Updates later today…
