through Tuesday night. A dry northwest flow will set up over the region over the next couple of day ahead of a strong ridge of high pressure that will move over the area by mid week. Overall winds will be much lighter across the area today, but there will be some remaining breezes down the Colorado River this afternoon. The big story over the next few days will be increasing temperatures. Highs today will jump about 5 degrees from yesterday and then an additional 5 degrees warming on Monday. This will put most areas about 5-10 degrees above normal by Monday and Tuesday. The models do indicate a couple of weak disturbances pushing southeast through Utah Monday and Tuesday. This may bring a few clouds to Lincoln and northern Mohave Counties, but any precipitation will remain well east of the area. .LONG TERM...Wednesday through Sunday. Strong ridge of high pressure will provide the region with warm temperatures Wednesday-Friday. In fact, warmest readings of 2017 expected with triple digits being easily reached in Death Valley N.P. While cities in the the lower Colorado River Valley from Laughlin/Bullhead City to Lake Havasu City have all reached 99 degrees so far this year. This week will be their first taste of triple digits. Ridge axis shifts east over the Rocky Mountain states as a deep trough approaches the West Coast Friday. Winds will increase from the south-southwest Friday likely making Friday the warmest day of the period. Models continue to advertise a deep trough developing over the southwest CONUS next weekend. Have higher confidence that temperatures will dramatically cool and gusty winds could be a problem. Less confidence in precipitation chances/placement due to large difference in position of upper low next Sunday. ECMWF has the low off the central California coast while the GFS is inland over California/Nevada. For now, keeping any slight chance mention of showers confined to the higher terrain of Inyo/Esmeralda Counties Saturday and Sunday.
