April 30, 2020/report

April 30, 2020

Summary: Even though temperatures will continue above average today, today will be a transition day for the beginning of a cooling trend which will lower temperatures to near seasonal averages over the weekend.  A dry cold front moved through central California during the early morning hours.  Its associated upper trough of low pressure is currently moving through.  As the system moves into the interior western U.S., barometers will fall over the Great Basin, setting up a roughly 15 mb difference in pressure between San Francisco and Las Vegas by late tonight and early Friday morning.

 

As a result, winds will begin to pick up out of the northwest and will become strong and gusty at times along the west side with areas of blowing dust becoming a problem by later this evening.

 

Temperatures this morning from Fresno County north are already anywhere from 5 to 9 degrees cooler than 24 hours ago.  The freezing level above Oakland has dropped about 2,800 feet over the past 24 hours.  Over the higher elevations, temperatures are substantially cooler this morning.  Sandburg, at an elevation of 4,100 feet is off 15 degrees from yesterday at this time.

 

A broad area of low pressure will dominate the pattern beginning today and lasting through the early part of next week.  The flow aloft remains west to east so any active weather will remain in the Pacific Northwest.  The trough will deepen somewhat Sunday into Monday, resulting in another round of gusty winds with temperatures actually marginally below average.

 

Models for next Wednesday and into next weekend are indicating a return of a strong ridge of upper level high pressure.  If these projections are accurate, we should see temperatures eclipsing the 90 degree mark again next Thursday.

 

Forecast: Mostly clear through Saturday night.  becoming breezy from late afternoon through Friday.  Mostly clear to occasionally partly cloudy Sunday through Monday night.  mostly clear Tuesday through Thursday.

Two Week Outlook: May 7 through May 13:  This model indicates a dominant ridge of upper level high pressure will be over the eastern Pacific and California, resulting in above average temperatures.  The chance of rain during this timeframe appears to be very low.

 

May:  The first month of the dry season will be typically dry, in other words this model is portraying near average precipitation for the month of May.  It also appears the trend of above average temperatures will continue for the month.

 

May, June, July:  Obviously, over the next 90 days precipitation will be largely nonexistent with the usual few exceptions, mainly during the month of May.  Models show the western half of the U.S. having generally above average temperatures.

 

Winds Discussion: Winds will be variable this morning to around 12 MPH.  Winds will pick up later this afternoon to 10 to 20 MPH along the west side with stronger gusts and 8 to 15 MPH elsewhere.  Winds tonight through Friday evening will increase along the west side to 15 to 30 MPH at times with local gusts to near 40 MPH possible, especially along the Interstate 5 corridor.  Winds elsewhere will be out of the northwest at 10 to 20 MPH with stronger gusts.  Winds Saturday will be mainly out of the northwest at 8 to 15 MPH then will increase again Sunday to 10 to 20 MPH with stronger gusts, especially along the west side.

 

Rain Discussion: Expect dry conditions for the next 7 to 10 days.
