.DISCUSSION...
For today through this weekend, some light rain showers could be
possible through this afternoon (20-40% chance) as well as
Saturday evening (20-30% chance). Any accumulations should be
fairly light, only around a couple hundredths, maybe up to a
tenth of an inch on the high end. Sunday will be fairly dry, with
afternoon RH falling to 30-40% and sunshine returning along with
NW winds gusting up to 20mph. Monday, a chance of rain returns
(30-40%), currently the best chance looks to be in the afternoon
and evening into early Tuesday. Rainfall rates should be fairly
light, but by Tuesday morning up to a couple tenths could have
fallen. This Monday system has been changing with new model data,
so confidence is low to medium at this point for rainfall
potential. Southerly winds with gusts of 15-25 mph are possible
Monday afternoon.
