Weather 6-18-19


Our weather today will feature a flattened zonal flow with the jet stream positioned directly overhead of Northcentral Washington bringing an intense pressure gradient the result is going to be dry and breezy/windy conditions with afternoon high temperatures still above normal into the mid 80’s. Expect west wind 15-20 mph with gusts by tonight approaching 35 mph. Because of the hot, dry and windy conditions, there is a red flag warning in place for most of Northcentral Washington from 2:00 p.m. today until 9:00 p.m. Thursday.

An upper level area of low pressure drops down from Canada on Wednesday with the result being another tight surface pressure gradient allowing for continued breezy/windy weather coupled with substantial cooling of 10 degrees Fahrenheit in comparison to today`s expected high temps. Sunny on Wednesday with west wind 10-20 mph with gusts once again around 35 mph. As mentioned earlier fire weather highlights are in place to address the concern for spread of any new and existing fires due to the dry and breezy/windy conditions.

The large weather system will basically be overhead on Thursday with mostly sunny skies, breezy conditions and high temperatures in the mid 70’s.

For the end of the week on Friday, the cold upper level trough will slowly slide eastward putting us under a northerly flow aloft.  Expect mostly sunny skies for the first day of summer on Friday with warmer temperatures into the upper 70’s to lower 80’s.

The weekend weather looks to be very nice with mostly sunny skies both days and afternoon high temperatures in the lower 80’s on Saturday and near 80 degrees on Sunday.

Monday and beyond, an upper level low originating out of the Gulf of Alaska will position itself somewhere along the British Columbia Coast come Sunday and will turn our upper level winds westerly. Beyond this, the forecast begins to diverge. Some weather models continue to track this upper level low down the West Coast on Monday while other models bring it inland or park it along the Washington coast. Depending on where this low sets up will ultimately influence our precipitation chances early next week and thereafter.
