August 3, 2019
Summary: Strong upper level high pressure is back over its typical summertime position over the Four Corners region of the Desert Southwest. The high has been slowly expanding towards the west and California is now on its western edge. Warmer locations this afternoon will move into the lower 100s with readings in the 100 to 105 degree range expected Sunday and Monday. The clockwise flow around the high has shifted the winds aloft to a southerly direction instead of the southwesterly flow of the past several days. Embedded within this flow are mid and high level clouds from the monsoon, however models indicate the deepest subtropical moisture will remain to our east so that is all we’ll see, just some high clouds at times. The real heat belt is over the lower deserts of southern California and Arizona where some locations will see temperatures above 115.
Readings will begin to slowly come down Tuesday as models show a low center developing west of the Oregon coastline. This will deepen the marine layer which currently is only 1,200 feet deep and will allow that modified sea breeze to lower temperatures further once we get to the Wednesday-Friday time frame. With a little luck, we should see temperatures in the low to mid 90s.
Some models indicate the high will move back to the Four Corners region by next weekend. On paper, this doesn’t appear to be a particularly strong system, so it would appear temperatures would only climb back up to seasonal levels.
Forecast: Occasional mid and high level clouds, but mostly clear skies will prevail through Tuesday and hot. Mostly clear Tuesday night through Saturday with a slow cooling trend.

Two Week Outlook: August 10 through August16: this model actually shows much of the U.S. enjoying below average temperatures. The exception is the western one-third where temperatures will be marginally above average. No precipitation is expected at this time.
August: This model projects fairly persistent upper level high pressure over the Desert Southwest. The monsoon shows up, as it typically does this time of year, but it generally produces little to no precipitation over the valley. The bottom line, temperatures will be marginally above average with typically dry conditions.
August, September, October: The 90 day outlook doesn’t really give strong indicators one way or the other. As far as precipitation is concerned, this model is projecting near average totals for the next three months. This model also projects above average temperatures for much of the western U.S.
Winds: Winds will be mainly out of the northwest at 5 to 15 MPH afternoons and evenings with local gusts to near 20 possible. Winds during the night and morning hours will be generally less than 10 MPH with periods of near calm conditions.
Rain: Expect dry conditions for the next week to ten days.
