Good Morning.
Today’s Forecast for the San Bernardino Mountains.
Onshore flow will continue today and Thursday. Some light fog may creep into the Valley for a brief period this morning. However, at this time (5am) it is clear below. Today will be pretty much the same weather wise as Wednesday was, temperatures in the upper 60s to low 70s across the Crestline and Lake Arrowhead areas. Big Bear and Running Springs will be in the low to mid 60s today. Overnight lows will be cooler across the area by a couple degrees tonight and more so Friday night as cool air from high pressure over the Great Basin flows in on a NE wind. Saturday we will have a return of Santa Ana type winds. Strengthening High Pressure over the GB will create a 10-14mb pressure gradient from Tonopah to San Diego. Winds will be gusty from the NE at 20-40mph Saturday through Sunday morning. By Sunday evening, the winds should taper off except over the ridges and canyon areas. West Coast troughing will be responsible for the strong winds, but fortunately as the progression of highs and lows pass through the North West, we should only see short duration Santa Ana wind events followed by a return to a more moist SW flow by Sunday. Saturday, we will likely see a RED FLAG Weather Warning for the SoCal region for about a 8-10 hour period during the morning through the afternoon hours. That’s it for today. As always, be Fire Safe especially this time of year. Thank You for joining me @
