What a difference a week makes

Brrrr!

A week ago, the desert was basking in normal fall temperatures, highs around 100°F, lows around 70°F. As usual at this time of the year, the skies were clear and humidity was low. In short, perfect desert weather.

Then, early in the week the weather service started warning of "...STRONG SEPTEMBER STORM POSSIBLE LATE THURSDAY THROUGH EARLY SATURDAY..."

— A STRONG STORM FOR SEPTEMBER MAY MOVE THROUGH SOUTHERN CALIFORNIA LATE THURSDAY THROUGH EARLY SATURDAY. THIS STORM HAS THE POTENTIAL TO PRODUCE WEATHER VERY RARELY SEEN IN SOUTHERN CALIFORNIA IN SEPTEMBER. THIS COULD BE THE STRONGEST MID LATITUDE SEPTEMBER STORM FOR SOUTHERN CALIFORNIA IN AROUND 20 YEARS. SEPTEMBER STORMS WITH SOME SIMILARITY TO THIS STORM OCCURRED IN 1986 AND IN 1963....

STRONG WINDS WILL DEVELOP IN ADVANCE OF THIS STORM IN THE MOUNTAINS AND DESERTS FOR WEDNESDAY NIGHT AND THURSDAY. THIS STORM SHOULD BRING MUCH COOLER TEMPERATURES FOR THURSDAY AND FRIDAY WITH COOLEST TEMPERATURES FRIDAY. DEPENDING UPON THE EVENTUAL TRACK AND TIMING OF THIS STORM... THERE IS THE POTENTIAL FOR LOCALLY HEAVY PRECIPITATION AT TIMES FROM LATE THURSDAY THROUGH LATE FRIDAY. THIS STORM WILL BE QUITE COLD FOR SEPTEMBER WITH THE POSSIBILITY OF THUNDERSTORMS AND EVEN FOR SNOWFALL IN THE MOUNTAINS ABOVE 6000 FEET.
weather alert

Turns out they weren't kidding! The really high winds haven't materialized at my house (they don't usually, it's protected by the canyon), but the temperature has been another matter entirely. For the past few mornings the temperature has been in the low 60s, a rude shock to the system. Yesterday, the high temperature was only 81°F!

It's enough to make a person look for long pants and sweatshirts! In fact, last night I briefly considered turning on the furnace.
