People don't like the intense marine layer in May and June here in Southern California, but we have July, August, September and October ahead of us and with El Niño, those months are sure going to be hot.

Today, some light drizzle added some water to our rain barrels, my morning run 🏃‍♂️ in sub-70℉ (under 20℃) temperatures was very enjoyable, and the light is nice and even for close-up and intimate landscape photography all day. 😊

#MayGray #JuneGloom #CAWx #SanDiego #Weather

North Pacific (35-60N) average sea surface temperatures have been rising since ~1980 and are uncorrelated with #ENSO. If, as expected, El Niño develops/persists through the coming Northern Hemisphere winter, storms will interact with #sst significantly higher than previous El Niños. More water vapor available through evaporation and the potential for stronger storms. Atmospheric rivers anyone? #akwx #bcwx #wawx #orwx #cawx #ExtremeWeather @Climatologist49

Snow melt will keep area waterways running very fast & dangerously cold. Even strong swimmers will be in danger. Do not enter cold, fast-running water & keep in mind these safety tips!

✔️Never go on the water alone
✔️Wear a life jacket
✔️Keep a close eye on children

It's a beautiful morning at #ForkedMeadow #California where the temperature is currently 40f. Overnight it went down to 36f but we haven't seen freezing conditions in several weeks now.

A Wind Advisory is in effect for the Mojave Desert Slopes from 7 PM PDT this evening until 1 AM PDT early Saturday morning. Blowing dust will reduce visibilities at times. Travel will be difficult, particularly for high profile vehicles. Highways affected include, but are not limited to Highway 14, Highway 178 below Walker Pass, and Highway 58 below Tehachapi Pass, including the town of Mojave.

The marine layer apparently stuck here in SoCal next week, still. NWS LOX: "A strong onshore flow pattern will keep a persistent and deep marine layer in place through next week. Night through morning low clouds and fog will with some afternoon clearing will continue as well. Drizzle or very light rain is possible each morning across coast and valleys.

An active spring thunderstorm pattern will continue in California's mountains, along with relatively mild temperatures. As occurred yesterday, a few of these scattered storms could make it into the foothills or fringes of the northern/eastern Central Valley. #CAwx https://t.co/dSFa0j5h0u

Current weather patterns in SF are stuck with Karl the Fog…Happy cool Friday.
If you get the fog to clear & in the sun, it's not bad but all locations are running well below average on temps. AM Drizzle too.

Not much clearing on the coast. It was warmer in SF yesterday (61) than Santa Cruz (60). Rare for May 24th.

Staying cool. #sfwx #cawx #NorCal

Persistence! Here are the maximum forecast temperatures for select cities across the Bay Area and Central Coast heading into the Memorial Day Weekend. #CAwx #BayAreaWX

Radar at 8:05 pm. Showers and thunderstorms are expected to continue over the northern half of the Sacramento valley and northern mountains through the evening. Continued brief heavy rain, lightning and small hail are expected with these storms. #CAwx #CAwx

Showers and Isolated thunderstorms continue over the mountains this afternoon. Activity over northern Shasta County may drift south over the north end of the valley this evening. #CAwx #CAwx

Slow going on Interstate 80 over the Sierra Nevada crest area with water and hail covered roadways. Expect slow going and potential slippery conditions over the passes this afternoon. #cawx #CAwx

An areal Flood Watch is in effect due to localized heavy rainfall with slow-moving thunderstorms this afternoon/evening.

Soils are already saturated, and area streams and creeks are running high. It will not take much accumulation to cause flooding issues today.

#nvwx #cawx

Showers & a few thunderstorms are ongoing across the region (as of 12 PM), w/ more to come this PM! T-storms will be capable of strong outflow winds, frequent ⚡️, small hail, heavy downpours & flash flooding!

Remember, when thunder roars, go indoors!
#cawx #nvwx

With the strong winds in Imperial County later this afternoon and evening, blowing dust is likely and could locally lower surface visibility. Please drive with care in western Imperial County if you encounter any visibility restrictions. #cawx

Patchy drizzle once again reported this morning (past 6 hours), especially in locations around Santa Cruz. Even picking up reports at Mt. Toro and Fremont Peak as well as portions of the East Bay hills. Any drizzle in your location? #CAwx #BayAreaWX

In honor of Safe Boating Week, we met with @USCG and SFFD partners earlier today to spread boat safety awareness. Main takeaways include: always wear a life jacket and check weather and sea conditions before going out on the water. See http://weather.gov/safety/safeboating-week for more. #CAwx

#MayGray is very stubborn and well inland today. However, there are indications of "reverse-clearing" where clouds erode first near the beaches. Some coastal sections will see sun at times this afternoon! Woohoo!! #CAwx #LAweather

Showers & storms will likely begin earlier than usual today, likely sometime in the late morning/early afternoon for W NV.
Possible ⛈️ hazards include strong winds, heavy downpours, some hail, lightning, & localized flash flooding. When thunder roars, go indoors!

Drizzle-fest 2.0 - just like Tuesday, moist upslope over the Santa Cruz Mts is leading to patchy drizzle. #cawx

Persistent May Gray will keep high temperatures anywhere from 3 to 10 degrees cooler than seasonal normal in the coasts and valleys today.

Meanwhile, the mountains and deserts are wondering "what May Gray?" as highs top out 3 to 6 degrees warmer than normal!

An upper level trough impacting the West Coast will result in cooler temperatures for your Tuesday afternoon. Look for upper 50s to lower 60s at the coast with upper 60s to 70s across the interior. These cooler conditions will persist through the week. #CAwx #BayAreaWX

The 5 PM satellite image showed marine layer clouds surging inland (again), and dissipating storms over the mountains and deserts. Tuesday will be a lot like Monday near the coast with more clouds and cool weather. The mountains and deserts will be dry. #cawx

Chance of showers & storms linger thru the weekend, with best chance Wed-Fri. Temps will slowly cool thru the week & feel more like late May warmth instead of early July! ⛈️☀️

The melt keeps rolling along at #ForkedMeadow #California. It only went down to 40f last night and is already 65f this morning. We've still got a chance for thunderstorms the next few days but so far the storms have stayed north and south of the #DinkeyCreek area.

Isolated to scattered showers and thunderstorms are expected this afternoon/evening and again on Sunday. Keep an eye to the sky and seek shelter in a building if possible. If not, a hard-top vehicle with windows rolled up is a good alternative. #LightningSafety #NVwx #CAwx

At this rate, there will only be a few banks of snow in the deepest shadows in the forest at #ForkedMeadow #California by the start of June! The overnight low was 40f and yesterday's high was 71f.

The meadow in this photo is at almost exactly 6000ft. But up at 9000ft, the melt hasn't barely started yet.

The parts of the meadows that have been snow free for several days are starting to green up at #ForkedMeadow #California. The overnight low was 37f and so far it's up to 64f with several more degrees to go today. Maybe there will be a bit of monsoonal moisture coming in over the next several days. #CaWx #Sierra #SierraNevada #Sierras #DinkeyCreek #ShaverLake #SierraNationalForest

While #ForkedMeadow #California might look to be mostly melted out from this photo, up in the woods there are still 8+ft drifts and deep tree wells. Yesterday's high was 68f and the overnight low was 35f. It looks like things will warm up a bit more over the next several days. The melt continues to pick up speed but there is still a LOT of snow left to melt at 6000ft and even more further up.

#CaWx #Sierra #SierraNevada #Sierras #ShaverLake #DinkeyCreek #SierraNationalForest

New Weather West post this PM on upcoming (prolonged?) warming trend across CA and active mountain thunderstorm pattern due to (extreme) high pressure blocking pattern developing over Western Canada. Quite an unusual setup for May... #CAwx #CAwater https://t.co/MZF31lKFjF

The melt is picking up speed again at #ForkedMeadow #California. Yesterday's high was 52f and the overnight low was 30f. Another few days and most of the meadows will be snow free at this elevation (6000ft). Only the pocket meadows that are normally heavily shaded will still have significant snow coverage. Up the hill, the snow is still deep so there's a lot more water to come down the creeks and head for the valley. #CaWx #DinkeyCreek #ShaverLake #Sierra #SierraNevada #Sierras
