.DISCUSSION...Today and tonight...
An uptick in storm coverage is expected this afternoon and
evening as moisture increases across the region, with scattered
wetting rains and strong to severe wind gusts expected with storms.
With the increasing moisture will come improvements to relative
humidity values despite another day of above normal temperatures.
RH is expected to remain above critical thresholds, and a few
stronger storms will be capable of producing localized heavy
rainfall.
LONG TERM DISCUSSION...Sunday through Wednesday...
RH values are expected to remain above critical thresholds through
mid-week, with daily afternoon showers/storms continuing, Despite
Saturday having the best chance for for wetting rains, we should
see some wetting rains through the week.
...Thunderstorms imply strong gusty erratic winds...
...All surface winds are 20-Foot...10-Minute averaged winds...
...CWR is Chance of Wetting Rain - 0.10 inch or more liquid...
...24 HR Trends are based on averages over the respective zone
groups and may not match the actual forecast values
shown in those groups...
