VERY VERY HOT EVERYWHERE...SUMS UP TODAY. FORECAST IN GOOD SHAPE...BUT MADE A MINOR UPDATE TO WARM UP A COUPLE OF PLACES SOME MORE TODAY AND TONIGHT. GRADIENTS TRENDING STRONGER OFFSHORE WITH A 592DM HIGH PARKED OVER THE REGION...AND WITH LOW TEMPERATURES VERY WARM THIS MORNING...DAYTIME TEMPERATURES HAVE A HEAD START. MANY RECORDS ARE LIKELY TO FALL...WITH TEMPERATURES A NUMBER OF DEGREES HOTTER THAN YESTERDAY. DOWNTOWN LA LOOKS LIKE A LOCK TO BREAK A RECORD FOR TODAY...WITH A HIGH AROUND 110 NOT OUT OF THE QUESTION...RESULTING IN THE WARMEST DAY IN OVER 20 YEARS. THE AIR IS REALLY DRY...AND HEAT INDICIES WILL REMAIN JUST UNDER EXCESSIVE HEAT THRESHOLDS...BUT THIS IS STILL A CONCERNING AND POTENTIALLY DANGEROUS HEAT WAVE. TO NO SURPRISE...RED FLAG WARNINGS LOOK GOOD AS THEY ARE...BUT MOSTLY FOR PROLONGED HOT AND DRY CONDITIONS...AS OFFSHORE WINDS ARE LOCALLY BREEZY AT BEST.

Potential exists for dry Lightning in south west CA with fhunderstroms predicted for the Sierras and Kern County Mountains and deserts later this week. Fire weather concerns are for dry lightning storms.
