SYNOPSIS. An upper level disturbance will bring chances for showers and thunderstorms to far southeast California and northwest Arizona today, with a few lingering storms possible in far eastern Mohave County Monday. A fairly significant pattern change is in store for the upcoming week, with breezy to windy conditions expected Tuesday, chances for rain mainly north and east of Las Vegas Tuesday and Wednesday, and a few days of cooler temperatures for the latter half of the week.
SHORT TERM. through Monday night. Early afternoon satellite loop showed thick mid and high level cloud cover over much of Arizona, with a very complex flow pattern evident. The large scale flow was cyclonic around the upper low, which was over far northern Sonora, and smaller scale swirls associated with a vorticity lobe and mesoscale convective vortices were noted over Arizona. The clouds were moving west to southwest in the large scale flow and thinning out as they reached Clark and San Bernardino counties. Convection was trying to develop over Mohave County, but was being suppressed by the lack of daytime heating thanks to the cloud cover. As the afternoon goes on, expect differential heating boundaries to form under breaks in the clouds, which should help scattered storms pop. Yesterday and Friday, isolated storms developed farther west than anticipated. Today, skies are mostly clear and surface dewpoints are near 50F over Clark and eastern San Bernardino counties, so increased mountain PoPs a little in these areas. The low will move slowly east and northeast tonight and Monday, with only a few wraparound showers or thunderstorms expected Monday in far eastern Mohave County. By Monday night, the long-advertised pattern change will begin as a strong trough rolls into the Pacific Northwest. More on that in the long term and fire weather sections.
LONG TERM. Tuesday through Saturday.
A fairly strong Pacific trough will edge into the Pacific Northwest region on Tuesday while dragging a cold front through the Great Basin and eventually the Mojave Desert Tuesday night into Wednesday. Ahead of this front, gusty winds and mild conditions can be expected, with the strongest winds across the favored wind belt from Barstow northeastward up the I-15 corridor. A few showers may also form with the front across mainly Lincoln and northern Mohave Counties. Behind the front, much cooler temperatures will follow with afternoon highs on Wednesday dropping 5 to 10 degrees below daily normals. Ensemble guidance has been trending deeper with some lingering energy late in the week which closes off and drops into Arizona by Friday. This will keep our region on the cooler side of normal through the end of the week, with temperatures only slowly returning to near normal by the weekend.
FIRE WEATHER. Models continue to indicate a trough moving through the Great Basin Tuesday. Jury remains out just how strong will the winds get and if critical thresholds will be exceeded across southern Nevada and northwest Arizona. Humidity values still look to stay above 15 percent across all of Mohave County and much of Clark and Lincoln Counties. There actually may be more concern for Esmeralda and Nye Counties as gusty north winds develop behind the cold front will humidity values potentially lowering to 10-15 percent. Will continue to monitor.
AVIATION. For McCarran . Light winds near the terminal today are leading to highly variable wind directions. Expect this won't have a great deal of impact on air traffic due to the light speeds. Nonetheless, expect a general easterly oriented wind to set up in the afternoon and return again to southwest near sunset. A few mid and high clouds can be expected through the TAF period as well. The chances of thunderstorm activity in the Peach Springs corridor is looking a bit less likely in terms of extent and strength. However, it is still worth noting that outflow winds from any storms in that area may affect the terminal in the very late afternoon and evening. Stay tuned for updates.
For the rest of southern Nevada, northwest Arizona and southeast California . Relatively light winds following twice-daily trends are expected at the remaining TAF sites. Smoke is impacting portions of Inyo County, including KBIH. KBIH specifically is expected to drop into MVFR conditions around 00z. IFR conditions are not out of the realm of possibility in the vicinity of KBIH and the rest of the Owens Valley overnight.
Isolated showers and thunderstorms in the southeastern portion of CA/NW portion of AZ will result in SCT-BKN clouds with bases above 10 kft at KEED and KIFP for most of the day. These storms may result in vicinity showers and/or thunderstorms later in the afternoon with the possibility of outflow winds impacting the terminals.
SPOTTER INFORMATION STATEMENT. Spotters are encouraged to report any significant weather or impacts according to standard operating procedures.
