SYNOPSIS. High pressure will intensify over Arizona and New Mexico this weekend, bringing dangerous conditions to our region through Monday. Temperatures will trend downward after Monday becoming more seasonal by the middle of next week. Afternoon breezes will persist each day, with minimal cloud cover and very dry conditions.
UPDATE. Mostly clear skies dominate the region today as high pressure dominates the region and will continue to build over the coming days. The Meadow Valley wildfire south of Caliente has grown to over 30k+ acres and southerly breezes and a deeply mixed boundary layer fostered a well ventilated smoke plume this afternoon visible on satellite imagery. I went ahead and added mention of smoke to parts of Lincoln county for tonight and tomorrow with similar conditions expected.
A very modest push of mid-level moisture will seep into our southern zones tomorrow but mid level temperatures will remain warm with little to no instability realized for any convective potential. As such, only expecting a minor increase in cloud cover, particularly from Las Vegas south and east. Temperatures will continue to warm, generally unphased by the minor uptick in atmospheric moisture content.
SHORT TERM. Friday and the weekend.
High pressure centered over New Mexico is forecast to expand and strengthen through the weekend. Temperatures in our area are expected to climb to around 5 degrees above normal on Friday and 8- 10 degrees above normal over the weekend. This prompted the Excessive Heat Warning issued previously for Sat-Mon which will be continued with this package as conditions will be hot enough to approach record levels in some locations. Decided to issue a Heat Advisory Sat-Mon for the Spring Mountains including Red Rock Canyon where moderate to high Heat Risk are indicated. A Heat Advisory is also in effect for the Sheep Range and elevations below 4500 feet in Lincoln County and northern Mohave County. Winds on Friday are expected to be similar to today with breezes expected to get a little stronger over the weekend.
LONG TERM. Monday through Thursday.
The pattern next week is forecast to change with low pressure centered over Canada and multiple shortwaves moving west to east along the U.S./Canadian border. This pattern acts to suppress the area of high pressure over the southwest early in the week and eventually moves it off to the east as we head through the week. Temperatures to remain very hot on Monday before trending down to more seasonal levels by mid week. The more impactful weather after Monday may be increasing fire danger with the potential for stronger breezes combining with dry conditions. The pattern also keeps monsoon moisture east of us through at least the middle of the month.
FIRE WEATHER. Critically dry conditions and afternoon breezes continue through the foreseeable future with poor overnight humidity recoveries expected. Temperatures will increase to dangerous levels over the weekend into early next week with temperatures trending downward after Monday. Fire concerns will increase as winds are expected to become a little stronger over the weekend and especially early next week.
