Incredibly moist air has been brought into southern Colorado behind a cold front last night with more on the way from the south today. This moisture will run into the mountains sparking thunderstorms that will slowly push east into the I-25 corridor then eventually the eastern plains tonight. Flash Flood Watches are in effect through 12am Friday with the mountains and burn scars most likely to see the effects from flooding. Storms will be very slow moving today, and that means many of you will see a very steady rain from the afternoon through the overnight hours with locally heavy rainfall amounts over an inch. Tonight the rain will end and after a day in the 80s and 90s, we’ll fall to lows in the 50s and 60s. For flooding just remember, heavy rains will collect in the usual spots, low lying areas that typically see the most run off and burn scar areas.
COLORADO SPRINGS: High – 83; Low – 58. Thunderstorms with heavy rain, lightning, and even small hail at times are expected from the early afternoon through the overnight hours. Flooding, or at least heavy run off, will be a concern over Colorado Springs through the low lying areas. Storms should last well into the overnight hours, drying up sometime between 10pm to midnight.
PUEBLO: High – 91; Low – 62. Hot through the early afternoon with heavy rain and storms likely towards the end of the day through the overnight hours. Most modeling holds off on rain till sometime after 4 or 5pm and then brings the heavier storms through the overnight hours, eventually ending around 10pm. Despite the heavy rain, flash flooding is a lower concern through Pueblo as that dry ground will try and soak up as much rain as possible.
CANON CITY: High – 88; Low – 63. Heavy rain and flooding remains a big concern through Fremont county. Flooding concerns are highest through the mountains in Fremont county but Canon City and the smaller towns to the east very well could see flooding from the afternoon through the overnight hours.
WOODLAND PARK: High – 75; Low – 50. Storms with heavy rain, lightning and flash flooding like nearly guaranteed for Teller county and Woodland Park. Storms will start in the area around 12pm and get heavier through the afternoon and early evening hours. Remember, flash flooding concerns are high through Teller county, especially in typical run off areas and the fresh burn scar near the high chateau fire.
TRI-LAKES: High – 70s; Low – 50s. Storm chances are very similar across the Tri Lakes area compared to Colorado Springs today. Storms and heavy rain should start showing up after 1pm today and slowly move off and on through the area into the overnight hours. Flooding concerns are fairly low but small hail and cloud to ground lightning are much more likely.
PLAINS: High – 90s; Low – 60s. Heavy rain with a few strong to even severe storms are expected later today through the overnight hours. Storms will form first over the mountains and have to slowly push east through the afternoon to reach the plains, so much of the rain is expected overnight. There will be a corridor of storms in the northern plains by the Palmer Divide that sees storms first this afternoon, severe weather is most likely in this area with strong winds and large hail. All rain across the plains will dry up around midnight tonight.
WALSENBURG/TRINIDAD: High – 80s; Low – 50s. Heavy rain and thunderstorms are expected through the area starting in the early afternoon across the mountains and pushing east through Walsenburg and Trinidad. Flooding will be possible, especially in the mountains west of the two cities. Thunderstorms and rain, periodically heavy, will last into the overnight hours and move very slowly.
WEEKEND OUTLOOK OR NEXT WEATHER MAKER:
As this system slowly leaves us tonight, a bit of moisture and energy will try and spark a few more thunderstorms for Friday, mainly across the high county. The weekend looks hot and dry but monsoon moisture tries to make a return this coming week with rain chances across southern Colorado improving by Wednesday.
