The warm, spring-like weather of today will once again go by the wayside as another aggressive cold front (the last in the series, for awhile anyway) moves through the region overnight and returns the region to below normal temperatures for a few days. But alas, have faith as latest extended model trends show the colder air to retract back to the northwest over Alaska, Western Canada and the Pacific Northwest during the coming weekend into next week (see 500 MB Jet maps below). After that however; extended guidance diverges on the first weekend of May; so get out and enjoy the much deserved warmer, spring weather as temperatures jump back into the 60s and 70s and possibly some 80s.
