Lots of Wind this Weekend; Severe Storms Possible Saturday Night
5:50 pm Thu 19 October 2017
The surface pressure gradient continues to tighten as a low deepens to our west while a high remains stationary to our east. This pattern will persist through Saturday night. Low-level moisture is rapidly increasing and lows tonight should not drop below 60. A few showers are possible Friday, primarily before 5 pm as a couple of weak troughs move overhead. Odds for rain during Friday night’s ball games are only about 10 percent, so we’re looking pretty good there.
A potent weekend combination of strong moisture inflow, a decent cold front and upper level support point to a classic shower and thunderstorm event. A few of these storms may produce damaging wind as they form into a squall line.
The model timing has been consistent for the past three days, making this primarily an overnight event. Stout northerly winds replace the southerly breezes behind the front with gusts, much like last Sunday, over 30 mph.
Next week should be dry from Sunday afternoon onward as northerly wind flow pushes surface moisture deep into the Gulf. A secondary front passing on Tuesday ushers in a rapidly building high-pressure zone which will make that a very windy day indeed.
A reminder that fire danger remains high due to lots of dried vegetation around, and all outdoor burning should be avoided during this windy spell.
