Area Forecast Discussion National Weather Service Denver/Boulder CO 330 PM MDT Mon Jun 3 2019 .SHORT TERM...(This evening through Tuesday) Issued at 238 PM MDT Mon Jun 3 2019 Scattered showers and thunderstorms have developed over the higher terrain of the mountains and foothills west of the Urban Corridor this early afternoon. This is in association with a weak speed max over the state ahead of a broad and weakening trough of low pressure over the desert southwest. In addition, a scattered batch of strong to severe storms have initiated off the Palmer Ridge and are slowly traversing into better moisture in the Platte River valley. Best low level moisture and ML capes do reside along both the Palmer and Cheyenne ridges and areas east of Fort Morgan. Along the Urban Corridor, will expect higher based gusty storms with gusts in excess of 50 mph thru 6pm. Strong to severe level storms will have the opportunity to develop along the Palmer Ridge and points closer to Kansas with better moisture. Watching for the potential of a dry boundary behind the initial wave of storms which could provide another focus for severe storms into early to mid evening east of a Sterling to limon line. Short term models indicate the back edge of the showers and storms ending over the Front Range in the 23z to 01z timeframe with a final push of convection, possibly associated with a dryline boundary, on the plains exiting the CWA after 03z. For tonight, out to our far distant southwest over southern CA, AZ and the northern Baja region, the near stationary trough of low pressure places much of CO under a ridging and subsident environment. For the mid evening and overnight period, will expect clearing skies as subsidence from the ridge as it holds firm over CO. With steady but weak southwesterly flow aloft ahead of the trough, indication of some mid and upper level subtropical moisture gets drawn northward into the desert southwest and CO mountains from convection firing over the higher terrain of Mexico. This will likely set an environment similar to today with showers and storms firing over the mountains by early Tuesday afternoon followed by another round of scattered showers and storms across the eastern plains. Flow aloft and shear remain fairly weak into Tuesday along with slightly less surface moisture to work with. To our north for late Tuesday morning, watching a cool front dropping south into the far northeast plains from a quick moving disturbance near the US/Canadian border. This cool surge feature looks to pool and raise ML capes into the 800-1600 J/kg range along the Cheyenne Ridge and may create a focus for stronger to severe storms out east by the time better surface heating arrives for mid afternoon. Otherwise, the main characteristic of storms for Tuesday, especially along the Front Range, will be gusty winds in excess of 50mph along with small hail near the foothills and stronger storms across the far eastern .LONG TERM...(Tuesday night through Monday) Issued at 330 PM MDT Mon Jun 3 2019 An upper level trough will drift slowly eastward through northern New Mexico on Wednesday with weak lee cyclogenesis developing near the Colorado/New Mexico border. This will allow low to mid level winds to be out of the east which will bring in moisture from the central plains. Precipitable water values will be near 1 inch across the urban corridor and slightly above 1 inch across the far eastern plains. When comparing these values to the sounding climatology for Denver, they are close to the max moving average which indicates well above normal moisture for the region. The good moisture combined with the very weak mean winds will allow any storms that form Wednesday to have the potential to produce moderate to heavy rainfall. At this time, the best forcing appears that it will be south of our CWA which should limit overall thunderstorm coverage. However, the general trend in the global models is to shift the trough more northwestward with time which could put our CWA under better forcing with more widespread storms if this trend continues. In addition, Thursday's weather will depend on the proximity of the trough with better chances for rain and cooler temperatures if the trough if farther northwest than currently predicted. If the trough is farther southeast of the current forecast, Thursday may be mostly dry with only a few isolated showers and storms. I trended my forecast toward the northwestern solution feeling that models are struggling to resolve the tropical disturbance in the Gulf of Mexico. Ridging will build over Colorado on Friday with substantial subsidence leading to warmer temperatures and mainly dry conditions. Lee cyclogenesis will develop over northeast Colorado on Saturday as the mid to upper level jet stream from a trough over the Pacific Northwest approaches the CWA. Models are showing the best moisture along the Cheyenne Ridge with a possible complex of storms developing in southeast Wyoming and moving into far northeast Colorado Saturday night. A cold front associated with this complex of storms will move through the CWA on Saturday night bringing cooler and drier conditions on Sunday. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 238 PM MDT Mon Jun 3 2019 Scattered storms will persist through the 22z to 00z timeframe in the vicinity of the terminals with gusty outflow winds being the main threat. Brief heavy rain and small hail will be possible with the stronger storms before a period of westerly surface flow behind the first wave of storms. For late this afternoon and into tonight will expect a transition back to a southerly surface component. && .BOU WATCHES/WARNINGS/ADVISORIES...

The main threats will be gusty winds to 50 mph, brief rain and small hail. There is a slight chance of a severe storm further east across the plains, mainly east of a line from New Raymer to Last Chance. The main impacts with these stronger storms will be hail up to 1 inch in diameter, heavy rain and damaging winds to 60 mph. Storms will diminish by later this evening with clearing skies overnight. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday Tuesday will be another warm day with scattered afternoon storms, but weaker than the previous days. A weather system will bring in cooler temperatures and slow moving storms Wednesday capable of moderate to heavy rainfall. These should mainly impact the plains, but if they occur in the mountains, this could enhance any snowmelt or add to swollen rivers. Thursday will be another cool day with isolated showers and storms before a warm up begins on Friday and into Saturday. A cold front is expected to push down Saturday night for a cooler Sunday. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed across the far northeast plains of Colorado after 2 pm.
