  increase early next week.

* Haze is possible today due to smoke aloft from fires in Baja
  California.

* Below-normal temperatures are expected today before rising to near
  normal and then above normal into the weekend.

.DISCUSSION...through Tuesday. Midnight satellite loop showed the
weakening upper low moving away to the east and taking the clouds
with it. Surface obs showed locally breezy winds and temperatures
near to slightly cooler than 24 hours ago. No meaningful change to
forecast reasoning. Areas of hazy skies can be expected again today,
but coverage should be less than yesterday, and still less tomorrow
as 500-300 mb winds turn more west northwesterly. Heights will
slowly rise over our area through Sunday as high pressure builds to
the east, pushing temperatures to near normal for late June by
tomorrow and above normal by the weekend. Monsoon flow is already
evident into New Mexico, and this should slowly push farther west
through the weekend. Models still agree on low pressure nearing the
California coast by Monday and Tuesday, but are still showing a wide
spatial spread with precip forecasts, reflecting continued
uncertainty in how much (if any) monsoon moisture will be pulled
west by this low. Slight chances for thunderstorms are in the
forecast for far eastern Mohave County as early as Monday, spreading
farther west on Tuesday. Forecast details will almost certainly
change between now and then, but the main message is that summer
thunderstorm season is on its way.
