Slightly cooler today… Warming throughout the week . . . Hurricane Hillary still may impact our WX over the weekend. First snow next week?

Today will be a little bit cooler than the last few days for Northern Utah but temps will still be 5-10 degrees above normal.  Weak cold front passed through last night bringing a few clouds and these slightly cooler temps.  Ridge will start rebuilding today with temps rebounding into the mid-80’s for the rest of the week.

Attention then turns to an interesting scenario developing over the weekend into next week.  Hurricane Hillary is slowly making is turning north in the Eastern Pacific and will move over Baja California by Friday and north into Southern Cal and AZ on Saturday.  The remnants are looking more likely to spread over the Great Basin on Sunday and Monday providing Utah with potentially heavy, widespread rains.  At the same time a weak front will be pushing in from the west, weakening as it approaches the California coast.  This front won’t have much moisture itself but my be able to aid in pulling moisture from Hillary north into our area, it may also cool down the atmosphere enough to lower snow levels and the higher peaks of the Wasatch may see there first dusting.

Once the moisture from Hillary clears, another stronger trof will move ashore in California giving the Sierras a good shot at some early season snow.  It will weaken as it crosses the GB, but may also give us a few inches of snow above approx. 9000 feet.

Of course, this is a long way out and a lot can change but it’s certainly an interesting WX scenario.
