It might be June with talk of warmth and humidity and severe weather with even rumors of tropical storms but SNOW is still on going in the mountains of Wyoming.
This out this radar off weather.com for yesterday.
To prove it’s no mistake, check out this WYDOT camera at Antelope Butte along Wyoming’s US route 14. Yes that’s fresh snow on the ground.
That snow falls within a fairly deep upper trough where temperature held some 15-25F below normal. Part of the same system which is bringing strong storms and flooding rains to the Southern Plains into Arkansas and Missouri.
Yesterday’s highs over the Desert Southwest!

Frost advisories are in place over a large portion of Wyoming for this morning.
This snow also fell on the same afternoon that Death Valley soared to it’s first 120 degrees of the year.
The marine layer held onto parts of the California coast yesterday which meant a classic ‘large spread’ in temperature from beach to desert. Low 70s at the coast, upper 70s in Downtown LA, mid-100s Palm Springs and 120 at Death Valley.
Here’s a current satellite image showing the marine layer back onshore over Southern California this morning. As the sun comes back up, so the fog which has penetrated some coastal valleys and canyons will burn back to the beaches through the morning. It should push offshore for most but areas such as Ventura, Oxnard may once again hold onto low clouds and fog much of the day. Another hot one, beneath blazing sunshine for inland areas.
California cools slightly (especially at the coast) through mid week thanks to a disturbance moving through. This will present a more penetrable, deeper marine layer which will be tougher to clear some areas including the LA Basin but burn off should still occur but later into the PM, holding highs in the mid rather than upper 70s. Beaches may stay in the 60s while deserts still climb into the low and mid-100s.
The bowling ball will continuing rolling SLOWLY east bringing big rains to the Tennessee Valley and Southeast.
Surface chart for the same period shows the heavy rains.
By late week, that system continues to bring wet weather to the Southeast with upper system behind keeping things lively on the S Plains while a new trough digs into the Pacific Northwest. This will bring cool, wet weather here but heights will be trimmed over the Deserts, holding temperatures close to average for early June.
As we skip forward towards next weekend and early next week, that PNW system digs a large trough into the West and in turn, MORE big rains will arrive into the nations midsection while the heat and humidity builds over the East.
The ECMWF at 192 shows a reinforcing trough into the West, keeping it cooler than normal.
The 500mb height anomaly for the same time says it all.
CFSv2 has been consistent with driving reinforcing troughs and cool downs into the Rockies, Plains and East. I think this will be a summer in which heat tries to build in the west, slide east, only to get squashed by troughs.
