Area Forecast Discussion National Weather Service Denver/Boulder CO 226 PM MDT Fri Jul 29 2022 .SHORT TERM...(This evening through Saturday) Issued at 219 PM MDT Fri Jul 29 2022 Storms will continue to form and move off the higher terrain into the evening hours. PW values remain high with little shear and weak steering flow. This will equate to storms that can produce a quick inch in 30 min. Current CAMs, especially the NAM nest which has initialized better than others suggest isolated storms could make it onto the plains around 5 pm and continue into the evening. Storms could produce small hail and lightning with gusty outflow winds up to 35 mph. Storms are expected to dissipate after 9 pm with some lingering clouds overnight. For Saturday, the upper level ridge will flatten out helping to disrupt the influx of moisture into the region. Precipitable water will decrease into Saturday with values around 0.5 inches over mountains and 0.8 across the plains. A weak circulation over Weld county could bring some low stratus to the area similar to Friday morning before burning off by mid-morning. The flow over the plains could advect some drier air onto the plains during the afternoon which could impact storm coverage. Still expect storms to form over the mountains by the afternoon but will maintain low pops across the lower elevations. Temperatures will continue to increase with highs in the upper 80s over the lower elevations and mainly 70s for the higher terrain. .LONG TERM...(Saturday night through Friday) Issued at 219 PM MDT Fri Jul 29 2022 Upper level ridge that's been over the western states slowly progresses eastward on Sunday. Airmass continues to warm with highs reaching the lower to mid 90s across northeast Colorado. There will be a slight increase in moisture and instability ahead of a weak wave for Sunday afternoon. This is expected to produce a few more showers and storms Sunday than on Saturday. Precipitable water values will be near an inch and CAPE of 300-700 J/kg are expected. This will lead to a brief heavy rainfall and the limited flash flood threat for the burn areas. The upper level high slowly moves east across the Central and Southern Rockies Monday. Drier and warmer conditions will accompany it. Precipitable water values fall to a half inch over the higher terrain to around three-quarters of an inch over the Front Range and eastern plains. Should see a few weak showers/storms over the higher terrain, otherwise dry conditions are expected to prevail. Temperatures continue to warm with highs in the mid to upper 90s expected across northeast Colorado. For Tuesday through Friday...the upper level high will reside over the eastern half of the country. This will produce a south to southwest flow aloft across Colorado. Expect monsoonal moisture to increase with this pattern. Will go with scattered/likely PoPs for most areas as there should be plenty of moisture available. Weak short wave troughs embedded in the flow aloft should produce stronger convection and numerous storms. A little to soon to pinpoint which day(s) this may occur. For temperatures, highs over northeast Colorado should climb into the lower to mid 90s each day. Tuesday looks like the warmest before the better moisture arrives with mid to upper 90s for highs across northeast Colorado. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1231 PM MDT Fri Jul 29 2022 ILS/MVFR conditions are possible between 21 and 01z with thunderstorms at area terminals. Winds will be out of the north to northeast then turn southeast to drainage by 05z. Storms could produce a short period of heavy rain with gusty and erratic winds with some gusting up to 30 mph possible. Storms to the east and north could also produce outflow boundaries that could impact DEN after 01z. && .HYDROLOGY... Issued at 219 PM MDT Fri Jul 29 2022 Moisture will decrease slightly on Saturday, however will keep the burn areas in a limited threat given the coverage of thunderstorms and lower storm motions. Storms will be capable of producing at least half an inch of rain in less than an hour and with saturated soils from the previous few days flash flooding will be possible. Moisture and instability increase a little Sunday ahead of a weak upper level. This should produce more thunderstorms than Saturday. A few of these storms may produce heavy rainfall. High pressure moves across Colorado Monday. Other than a few weak storms over the higher terrain, dry conditions will prevail. An active thunderstorm pattern may return Tuesday and for the rest of next week. South to southwest flow around the high to the east should transport enough moisture into the area for at least scattered thunderstorms each day. && .BOU WATCHES/WARNINGS/ADVISORIES...
