SYNOPSIS

22/201 PM.

Hotter than normal conditions will continue through at least early next week, especially starting Thursday. The hot daytime and warm night conditions will bring elevated risks for heat illness. Thursday through Sunday will generally be the hottest of the next seven days. Gusty north winds will affect some areas through Friday.

LONG TERM (SUN-WED)

23/308 AM.

The upper high will begin to move back east on Sunday. More importantly there will be an increase in the onshore flow and possible return of some morning low clouds across the csts. The low but non-zero threat of monsoon convection will remain over the mtns. Max temps will drop a few degrees but advisory level heat will continue.

Hgts fall some on Monday as the upper high continues to move to the east. Onshore flow continues to increase. This will bring a few more degree of cooling. There may be enough cooling to consider dropping a few areas from the heat advisories, but for now its prudent to leave them all in through Monday evening.

More cooling on Tuesday should be enough to eliminate the heat threat. By next Wednesday highs will still be above normal but only by 3 to 5 degrees.

Mdls remain consistent showing another round of heat developing at the end of next week.
