Today will see lower dew points and humidity values thanks to some light northwesterly winds so it will feel better out there and your evaporative coolers should work better. The monsoonal moisture will remain just off to our East through tomorrow before making another incursion into the Valley. That incursion will lead to a chance

The monsoon moisture we’ve experienced most of the week is pushing farther to the East so it feels drier out there today. Dew points are slowly dropping, meaning your evaporative (swamp) coolers will function more efficiently into the weekend. Winds out of the North and West will are the main mechanism helping to dry out

The humidity remains thick, and there are some mountain thunderstorms in San Bernardino county. The dew points remain quite high through early tomorrow before the drying begins. The source of the moisture is a ridge of high pressure pulling in monsoonal flow from the south and east. A major driving force of the drying to

Humidity levels and dew points are on the rise this morning as we remain under an Excessive Heat Warning through this evening. The dew points are predominantly in the 70s this morning, and will remain in the 50s and 60s through the day, prompting the possibility of scattered showers today in the mountains and high

The heat is increasing but at least the humidity will slowly dry out over the next 24 hours. Late this evening dew points should start to feel better. The ridge of high pressure is still pulling in moisture from southeast of the Valley, so it will still feel pretty oppressive today. Highs will range into

Dew points continue to rise as we move through the morning, so the heat will feel worse today. Dew points will remain in the 50s and 60s through tomorrow afternoon, evaporative coolers won’t be the solution for cooling today or tomorrow, so if necessary, head to your local cooling center. A ridge of high pressure

After 115 yesterday, we’ll see similar numbers this afternoon. Humidity into Thursday and Friday may shave a few degrees off the highs prior to a very hot weekend. An Excessive Heat Warning is up for the high desert and an Excessive Heat Watch covers the Valley Saturday and Sunday. Drier air is slowly retreating, but

Highs yesterday topped out at 113, and we’ll see similar numbers through midweek. An Excessive Heat Watch will go into effect at 8 a.m. Wednesday, lasting through 8 p.m. Monday of next week due to the expected extreme heat. In addition to the heat this week, a little touch of monsoonal moisture is likely to

Skies are clear this afternoon and humidity values are lower along with the dew points, so it feels better out there. A bit of a NW breeze is helping to dry the atmosphere out and it will remain breezy this afternoon, especially North of the freeway. Temps under a ridge of high pressure continue to

Dew points are starting to fall a bit this morning as the atmosphere slowly dries out. Moisture is still gradually moving eastward. Daytime highs will top out near 110 for the next several days, and humidity values should be slightly lower than they were all week. This means you should be able to use evaporative

Dew points are still quite high, but will gradually drop over the next 36 hours, paving the way for a more comfortable holiday weekend despite warmer temps. The moist airmass over the region is gradually giving way to drier air moving in from the West. This process will be slow, but it is already noticeably

Thunderstorms still popping up to the north and east of the Valley with a very active cell this morning near Lake Havasu. You can see the frequent lightning strikes happening. Humidity remains thick across the region this morning, and it will linger through the day, much like yesterday, but the impetus for storms seems to

It’s not the heat, it’s the humidity (at least today and tomorrow). Monsoon moisture is on the increase, already dropping temps in the valley after clocking at high of 117 yesterday (just below the 118 record). Humidity will make it less comfortable today, despite the cooler highs. Evaporative coolers won’t work well today, and you

Highs yesterday hit 109, besting the previous record of 108 in Palm Springs, and making us the hottest place in the U.S.! Today we’ll see similar conditions as high pressure continues to keep highs well above average. Because of the heat, potential for gusty NE winds, and low humidity, Heat Advisories and Red Flag Warnings

Highs finally stayed below 100 and will do so again today. A large area of low pressure will keep cooler air flowing in the region. The winds have shifted, so there may likely be more smoke to contend with in the Valley today, so the SCAQMD has extended the Smoke Advisory through tonight. Despite that,

A Smoke Advisory remains in effect, but winds have shifted and skies are a great deal clearer than yesterday, though air quality is in the moderate range. Offshore “Santa Ana” winds developed overnight, but are relatively mild. The winds have prompted both Wind Advisories and Red Flag Warnings for the region. Dew points are sharply

A mixed bag of weather to report, with a Smoke Advisory in place again today, and lower Air Quality as well. Surrounding the Valley, Red Flag Warnings are in effect for much of the region, as moderate Santa Ana winds develop. Those winds will dry out dew points and increase fire danger. Those winds will

The Excessive Heat Warning remains in effect until 8PM, and a Red Flag Warning covers much of SoCal as well. Labor Day Weekend has delivered lots of record highs so far, and that will likely continue today: Offshore winds will develop for the Inland Empire and Coastal areas, but we’ll see some relief from the

An Excessive Heat Warning, which we’ve discussing all week, comes to fruition today at 10 a.m. and continues until Monday evening at 8. Highs will threaten existing records throughout the weekend. The culprit: High pressure over the Great Basin, generating record heat for much of the Desert Southwest through Tuesday before breaking down and moving

An Excessive Heat Watch (to become a Warning) will cover most of California, a lot of Nevada and Arizona as we hit the Labor Day Weekend. Drink plenty of water, avoid the heat of the day, and never leave a person or pet in a vehicle! A broad and expansive ridge of high pressure takes
