Area Forecast Discussion National Weather Service Las Vegas NV 1040 AM PDT Wed May 22 2019 .SYNOPSIS...A potent low pressure system will affect the entire region today by generating scattered showers and isolated thunderstorms before it slowly lifts away late Thursday. Expect cool conditions today with high temperatures around 25 degrees below normal. A warming trend follows heading into the weekend as temperatures on Saturday will be around 20 degrees warmer than today. The next upstream system is expected to bring more cool and unsettled weather to the area late in the weekend into early next week. && .UPDATE... Showers and isolated thunderstorms developing this morning across mainly portions of southern Lincoln, Clark, Mohave and San Bernardino Counties. Conditions are moderately unstable this morning with LI's generally ranging from 0/-2 across the region and with the cold upper low currently overhead, look for these showers and thunderstorms to continue . With a cold upper low directly overhead look for additional showers and isolated thunderstorms through the afternoon. Brief heavy rain, small hail, and gusty winds will be possible with any storm. There could be some isolated nuisance flooding around, but the flash flood threat is low. Current forecast in good shape and no updated planned. && PREV DISCUSSION 239 AM PDT Wed May 22 2019 .DISCUSSION... Today could get interesting with a cold upper low dropping directly over the forecast area. Temperatures look unseasonably cool with highs this afternoon expected to be around 25 degrees below normal. Much of the area will see rain showers and mountain snow as well as isolated thunderstorms with LI's generally 0 to -2 coupled with steep lapse rates. Snow levels start out around 5500 feet in the morning rising to around 7000 feet in the afternoon will lead to snow accumulations at elevations lower than normally expected for this time of year. Total snow amounts of 6 to 12 inches are possible above 7000 feet over the course of the next couple of days. The low slowly shifts east tonight before lifting off to the northeast Thursday. Moisture and lift associated with energy across the Great Basin will keep a chance of showers going over our northern areas Thursday and Friday. Temperatures begin to moderate Friday and Saturday but will still be 10-15 degrees below normal. No significant wind is forecast through the end of the week. The next upstream system is forecast to drop out of the Pacific NW this weekend and move south along the coast into early next week. Expect a drop off in temperatures and the possibility of more showers as this system draws near. && .AVIATION...For McCarran...A messy period is in store. Chances for showers and low ceilings will increase during the day today and not completely go away until Friday. The greatest risk of ceilings below 050 looks like tonight through Thursday night, but it cannot be ruled out today, especially if a heavier shower moves over the terminal. For the rest of southern Nevada, northwest Arizona and southeast California...Chances for rain and mountain snow showers and low ceilings will increase during the day today and not completely go away until Friday. The greatest risk of low ceilings and terrain obscuration looks like tonight through Thursday night, but it cannot be ruled out today, especially in heavier showers. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Salmen AVIATION...Morgan For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
