Area Forecast Discussion National Weather Service Pueblo CO 346 PM MDT Tue Jul 24 2018 .SHORT TERM...(This evening through Wednesday) Issued at 311 PM MDT Tue Jul 24 2018 Currently... At 2 pm...Radar was showing precip mainly along the mtns across most of the region. Best coverage was over the San Juans east of Wolf Creek. Temps over the region were much cooler, with 70s and L80s over the plains and 70s valleys. Dewpts remained high across the plains with readings in the 60s. Over the higher terrain the dwpts have increase a bit, with 40s and 50s in the valleys and 30s and 40s in the mtns. Rest of Today... Plenty of moisture is in place and the grounds are saturated, so its not going to take much to cause problems for flash flooding. However guidance is pretty persistent at keeping the heavier precip over the mtns. In the short term (mid afternoon), heaviest precip is expected to occur over the San Juans. by mid to late afternoon heaviest storms are anticipated to occur over the southern Sangre De Cristo mountain region. This will place the burn scars in the Sangres under the gun, and a Flash Flood watch is in effect for these regions. By late this afternoon some stronger convection develops in and around the greater Pikes Peak region, and this area will have to be watched due to the heavier rains that fell over Teller county and the sw parts of El Paso county. As for the plains....most of the activity will move across the region during the evening hours. Storms do not appear to be all that strong and they should move, however this area had also received heavy rain yesterday and these areas will have to be watched. Storms may not move into KS until shortly after midnight. SPC has area in marginal risk so there is a chance of some marginal svr wx on the plains tonight. A few isold storms may linger in the mtns tonight. Tomorrow... Main concern is the boundary coming down the plains that will move into the Pikes Peak area late in the day. Temps will be on the rise tomorrow and expect 90s over the most of the plains by afternoon. As front comes down the plains, thunderstorms will be on the increase. Talked to WFO BOU re: Flash Flood watch, and we decided to hold off on issuing any flood hilites until for now. For the rest of the region, storm coverage tomorrow will likely be a bit more widespread than today and plenty of monsoon and llvl moisture will be in place, so locally heavy rains will once again be possible. Storms will likely be over the I-25 corridor region by the late afternoon time period. SPC has parts of the plains in Marginal risk for svr, and this looks reasonable as shear will be on the increase; WPC has the area in Slight for flooding tomorrow afternoon. .LONG TERM...(Wednesday night through Tuesday) Issued at 311 PM MDT Tue Jul 24 2018 ...Active Pattern Will Remain over Southern Colorado... Forecast model runs over the past 24 hours show very little change from previous forecasts. Large scale pattern will remain similar to what we are currently seeing through the weekend. The main drivers of the pattern are a large and persistent area of high pressure covering the southwestern U.S. and a series of weak upper disturbances tracking by across northern Colorado. The disturbances act to trigger and focus convection across southern Colorado when deep, monsoonal moisture is in place this time of year. We will these focusing mechanisms repeat daily through the weekend. The details of the convection will be different each day, depending on the exact track and strength of the shortwaves moving through. Also, the placement of the previous day's convection will have impact on the placement of the next day's convection. So, these details will have to be refined each day. But, suffice it to say, parts of the area will be impacted almost daily through the weekend. Primary concerns will continue to be heavy rain and flash flooding, particularly for burn scars and urban areas. However, shear will be sufficient for some severe weather at times as well, involving hail generally up to quarter size and downburst winds gusts up to 60 mph or more. The first real chance at drying doesn't look to arrive until early next week, particularly by Tuesday. At the time, forecast models indicate amplification of the ridge over the western U.S. which would bring in drier air from the north and generally increase the amount of subsidence over the region. But, that is still a long way off and remains to be seen. && .AVIATION...(For the 00Z TAFS through 00Z Wednesday evening) Issued at 311 PM MDT Tue Jul 24 2018 KCOS: TSRA possible this afternoon and tomorrow afternoon, otherwise VFR expected. Gusty winds and small hail possible with storms both days. Locally heavy rain with brief IFR possible. KPUB: TSRA will likely be in the vicinity later this afternoon/evening at KPUB with a better chance of TSRA affect the airport tomorrow. KALS: ISOLD tsra possible both this afternoon and tomorrow afternoon with gusty winds and small hail possible. Otherwise VFR. && .PUB WATCHES/WARNINGS/ADVISORIES...

The main threat from storms will be locally heavy rain. With grounds already saturated from rains yesterday, localized flash flooding will be possible. Burn scars, especially from highway 50 south to the New Mexico border, will be highly susceptible to flooding today. One or two of the storms on the plains will also be capable for producing wind gusts to 60 mph and hail up to the size of nickels. .DAYS TWO THROUGH SEVEN...Wednesday through Monday A pattern of abundant moisture and disturbances embedded in northwest flow is forecast to remain in place through the next week. This setup will lead to daily thunderstorm chances across the mountains and plains, particularly over the eastern mountains and plains. The main threats with storms each day will be wind gusts up to 50 mph, small hail, lightning, and heavy rainfall. Some stronger storms may produce hail over 1" and winds to 60 mph. Flash flooding will be possible each day, especially over recent burn scars and urban areas. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible this afternoon and tonight across the eastern mountains and adjacent plains. Hodanish
