DISCUSSION
BROAD HIGH PRESSURE REMAINS CENTERED JUST OFF THE
CALIFORNIA COAST THIS EVENING, BUT IT HAS MADE NOTICEABLE EASTWARD
PROGRESS SINCE THIS MORNING. IT WILL CONTINUE ITS EASTWARD TREK
THROUGH TOMORROW BEFORE PARKING OVER NORTHERN ARIZONA. THE
PRESENCE OF THIS RIDGE, RATHER ABNORMALLY STRONG FOR THIS TIME OF
YEAR, WILL BRING HISTORICALLY HOT TEMPERATURES FOR THIS TIME OF
YEAR, WITH MAXES RUNNING 25-30F ABOVE CLIMO. THE HOT WEATHER WILL
CONTINUE THROUGH SATURDAY BEFORE THE RIDGE SHIFTS EAST SUNDAY,
ALLOWING FOR THE PASSAGE OF A DRY COLD FRONT. WHILE THIS WILL MAKE
TEMPERATURES SIGNIFICANTLY LESS WARM, PARTICULARLY FOR NORTHERN
PORTIONS OF THE AREA, SUNDAY'S HIGHS SHOULD STILL AVERAGE 10-15F
ABOVE SEASONAL NORMALS.
HERE ARE THE LATEST PROBABILITIES OF BREAKING SOME NOTABLE HIGH
TEMPERATURE RECORDS FOR THE MONTH OF MARCH, PER NBM 5.0:
* KSLC (80 - 2010): THERE IS A LESS THAN 10% CHANCE THIS MONTHLY
RECORD IS REACHED WEDNESDAY, 50% THURSDAY, AND A 95% CHANCE
