Area Forecast Discussion National Weather Service Pueblo CO 312 PM MDT Sat Jun 13 2020 .SHORT TERM...(This evening through Sunday) Issued at 311 PM MDT Sat Jun 13 2020 Mid level moisture has increased across the area today, as upper level ridge drifts east and flow aloft strengthens ahead of wrn U.S. upper trough. Low levels remain rather dry, with dewpoints in the 20s/30s at most locations and T/Td spreads of over 50f on the plains, suggesting rainfall will be spotty and light despite moderate storm coverage so far this afternoon. Still a risk of a severe wind gust or two with any stronger storms, especially back over the mountains where instability is slightly better. Storms will continue into the evening, with HRRR suggesting most activity dying before it reaches the far ern tier of counties near the KS border. Sunset should bring a downturn in convection, though models hint at at least isolated showers lingering over much of the high terrain past midnight. Will keep Red Flag Warning in place into the evening for the eastern plains, as strong winds/low RH continue for a few more hours. Upper flow turns more wly on Sun as nrn Rockies wave lifts nwd into Canada, with drier air spreading across much of srn CO. Still some lingering moisture and afternoon tsra over srn mts and portions of the ern plains, though activity looks to be fairly spotty and weak given decreasing moisture. Deep mixing, drier air mass and more wind are expected Sun, and Red Flag conditions will be more widespread across the area, and will retain current warning for Sun afternoon and evening. Hot max temps will continue, with readings approaching 100f over the lower Arkansas Valley. .LONG TERM...(Sunday night through Saturday) Issued at 311 PM MDT Sat Jun 13 2020 Sunday night into Wednesday...An upper-level low is anticipated to sit and spin over the Pacific Northwest into the early part of the week before finally moving eastward late in the day Tuesday into Wednesday. A trough associated with this upper-level low is expected to keep us in a southwesterly flow regime, which is anticipated to bring daily chances for afternoon thunderstorms to the mountains. Additionally, the lower elevations should stay unseasonably warm (temperatures running 5-10 degrees F warmer than average) and breezy, causing prolonged critical to near critical fire weather conditions through midweek. Have gone ahead and issued a Fire Weather Watch for Monday afternoon and evening. Fire weather highlights will probably be needed for Tuesday as well, but will wait until we are closer to Tuesday to do so. Highs are expected to reach the mid 90s to around 100 across the plains each day, while the high valleys should see highs generally in the 80s. Thursday...The upper-level trough is anticipated to continue propagating eastward into the northern Great Plains, sending a cold front through our region. This cold front is expected to provide some, albeit minor, relief in temperatures. Highs across the plains are expected to be in the low to mid 90s and highs in the high valleys should remain in the 80s. There is also potential for the front to spark some showers and thunderstorms across the plains. With CAPE values potentially approaching 1000 J/kg, and depending on the timing of the frontal passage, a strong to severe storm is possible over the eastern plains. Friday and Saturday...A trailing trough is anticipated to develop behind the aforementioned trough over the Canadian Rockies, then translate across the northern U.S. Rockies. As a result, isolated to scattered showers and storms are anticipated to develop over the mountains around midday each day, then the chances for precipitation spread to the lower elevation, but confidence is low this far out to determine how great those chances will be. For now, have left isolated PoPs in the forecast. Highs stay in the 90s for the plains and 80s for the high valleys each day, with Saturday shaping up to be ever so slightly cooler than Friday. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 311 PM MDT Sat Jun 13 2020 Will continue VCTS mention in all tafs into the evening, though with dry low levels, gusty and erratic winds will be the main storm threat. Precip tapers to showers toward sunset, then ends overnight. VFR expected on Sun, with just a slight chance of a weak tsra in the afternoon, with perhaps some convective outflows impacting KCOS and KPUB late in the day. && .PUB WATCHES/WARNINGS/ADVISORIES... Red Flag Warning until 8 PM MDT this evening for COZ231>237. Red Flag Warning from noon to 8 PM MDT Sunday for COZ220-222- 226>237.

Thunderstorms could become strong to severe across the mountains with gusty winds up to 60 mph, locally heavy rainfall, and small hail possible. As thunderstorms move into the Interstate 25 corridor, they will weaken, with gusty erratic winds up to 50 mph, lightning and spotty light to moderate rainfall possible. Dry and windy conditions will spread across the southeast plains this afternoon where critical fire weather conditions will develop by afternoon. Low relative humidity, winds gusting up to 40 mph and dry vegetation will result in conditions favorable for rapid rates of fire growth and spread. Any activities which could start a wildfire should be avoided today. .DAYS TWO THROUGH SEVEN...Sunday through Friday A Red Flag Warning is in effect Lake, Chaffee, and Fremont Counties, as well as all of the eastern plains for Sunday, while near critical fire weather conditions are expected across the remainder of the area. Dry conditions continue on Monday through Wednesday, with critical and near critical fire weather conditions expected each day. A cold front is expected to pass on Thursday bringing showers and thunderstorms over the region. Thunderstorms are possible Sunday afternoon, but the majority of the storms that form will likely just produce virga, gusty outflow winds, and dry lightning. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible today across the mountains. 10/SKELLY
