Through next week...

A dry post frontal airmass will keep temperatures seasonable today
with highs in the 60s and lows in the 40s overnight tonight. This
will be short lived however, as ridging builds in from the west this
weekend. This will bring about drying reinforcing air and promote
above normal temperatures once again this weekend with highs in the
70s. Temperatures and dewpoints will continue to steadily increase
early next week with some 80s possible as ridging shifts east,
reestablishing southerly flow.

This southerly flow, in conjunction with a shortwave trough over
the southern plains making its way into the area, will support
increased rain and storm chances Monday and Tuesday. At this time,
any chance for severe or damaging convective activity looks to be
limited given the lack of instability and most forcing being
deflected to the north with SE ridging holding strong. Some
thunderstorms will be possible along the attendant surface cold
front as it passes through the area, most likely Tuesday evening.
This cold front looks to mark a much greater pattern shift
characterized by far cooler/colder temperatures. Blocking
downstream (-NAO) along with a building ridge over the Pacific
northwest (+PNA), should force a Canadian high south towards our
area. First freeze of the season is becoming increasingly likely
possibly by late next week. There is still some uncertainty at
this time with the evolution of the synoptic pattern. Should the
lead shortwave eject quicker with less phasing, there could be a
second wave that could delay the freeze to beyond the forecast
period and potentially promote a secondary chance for severe
weather. Given this is still at the end or just after the forecast
period, expect updates and adjustments as details come into
focus./SAS/OAJ/
