Gosh, it hasn't rained since Oct. 4th (24 days) so any chances for showers should be welcomed...except if they come on this Halloween weekend. Models are showing and NWS is indicating high rain chances for Saturday PM into Sunday midday. Now it's hard to disagree with our improved model technology, except my past experience tells me it's often hard to break out of a dry spell unless there is a "Triggering Mechanism" (surface front, upper disturbance). Let's begin with the NWS thinking.
I agree with their "Rain? Seriously???" 70% on Saturday PM is pretty aggressive when there is no cold front involved. I like to track features on satellite loops, but all the features are far away from us. There is a strong upper low NW of Seattle, the remains of Trop. Storm Vance moving into Mexico and the hints of moisture spreading from Hawaii with the sub-tropical jet stream (Hawaiian Express).
But where is the trigger to produce showers for us this weekend? We have no fronts around.
We do have the surface high off the East Coast with a warm bubble of air all the way up to Green Bay. 70+ dew points are showing up over south Texas so low level moisture is on the increase. But what will trigger our weekend showers? Models show it. NWS is forecasting it, so all local stations are calling for it. I'm just tossing out the past issues of breaking out of dry spells. I'd like to see something on satellite/Water Vapor loops to confirm what models are showing. Aside from the remains of Vance, I don't see much to trigger 70% rain chances. We'll see.
Right now, radar is seeing a few showers heading into Texas. Compare that to the moisture with the remains of Vance moving into Mexico. I believe that moisture from Vance moves into Texas & Oklahoma and stays to our north and west. Just trying to figure out what will break our current drought. When in drought, leave it out.
I think the only thing certain regarding this weekend is the TIME CHANGE. We set our clock back one hour before you go to sleep Saturday night (Fall Back). Tomorrow's podcast is about my trip back to Orange Beach after Hurricane Isaias.
