SYNOPSIS
Above normal temperatures continue today. A dry cold front will move through the region late tonight into tomorrow bringing breezy to locally windy conditions to the region. This cold front will also drop afternoon high temperatures to near to slightly above normal tomorrow and drop Wednesday morning low temperatures into the 30s and low 40s, some rural desert communities will see temperatures near or slightly below freezing. Temperatures will then quickly rebound back to 3 to 5 degrees above normal for the second half of the week. Dry conditions will continue through the next week.
DISCUSSION
Objective 500 mb streamline analysis shows quasi-zonal flow over the Desert Southwest, a clipper system moving through the Dakotas and a secondary trough axis behind the clipper system starting to dig into northern Nevada and Utah. The aforementioned clipper system and secondary trough have allowed heights aloft to relax a little bit which will lead to temperatures a couple degrees cooler today than what we saw yesterday. This afternoon temperatures are forecasted to top out in the low-to-mid 70s across the lower deserts and in the mid 60s across the higher terrain areas.
Heading into this afternoon and evening the secondary trough will continue to dig into the Four Corners Region sending a dry cold front through our region. This will lead to breezy to locally windy conditions across the area this evening through tomorrow morning, with the strongest winds expected in southeastern California and along the Lower Colorado River Valley. The strongest winds will occur during the overnight hours and thus will make it difficult for them to mix down to the desert floor and thus only wind gusts of 25- 35 mph are expected across the lower elevations. Wind gusts up around 40-45 mph will be possible (60-90%) for the higher elevations/ridgetops of southeastern California (e.g., the Chocolate Mountains). In addition to the breezy and windy conditions the cold front will also usher in cooler and much drier air (PWATS near 0.1"). This will allow for a brief cool down on Tuesday with afternoon high temperatures forecasted to be near/slightly above normal (mid 60s across the lower deserts and 50s for the higher terrain areas). Wednesday morning will be the coldest morning of the week thanks to the combination of clear skies and the post-frontal cooler and much drier air. Wednesday morning low temperatures are forecasted to drop into the 30s and low 40s with the typical cooler more rural areas possibly seeing temperatures dip into the upper 20s. A Freeze Watch has been issued for Wednesday morning for the Lower Colorado River Valley, portions of northwest Pinal County, particularly the Casa Grande and Arizona City areas, and the Globe/Miami and San Carlos areas.
The NBM now gives a 60-100% chance of these areas at least reaching the freezing mark. The Arizona City and San Carlos communities have a chance of seeing a hard freeze as they are currently forecasted to see temperatures in the 26-28 degree range. For folks in the communities with a Freeze Watch, make sure to practice the 4 P's; protect people, pets, pipes, and plants from the cold, Tuesday night/Wednesday morning.
Ridging will quickly build back in over western CONUS on Wednesday resulting in temperatures going back above normal. This ridge won't be as strong thanks to a couple troughs moving into the Pacific Northwest by the end of the workweek and next weekend. Although these troughs won't relax the heights aloft enough to see our temperatures cool to near normal, it will keep temperatures only around 3-6 degrees above normal rather than around the 10 degrees above normal that we saw last week. Dry conditions persist through next weekend.
