Area Forecast Discussion National Weather Service Denver/Boulder CO 846 PM MDT Sun Apr 21 2024


- Warmer on Monday with a slight chance of afternoon showers and isolated thunderstorms.

- Potential for stormier weather pattern starting late Thursday into next weekend.

Issued at 845 PM MDT Sun Apr 21 2024

Minimal updates this evening. Made minor refreshments to the sky grids to better reflect current stream of high clouds pushing into northeast Colorado.

SHORT TERM /Through Monday/
Issued at 221 PM MDT Sun Apr 21 2024

After multiple days of continuous cloud cover, skies have finally cleared out this aftn. Tonight, mid and high level moisture will move in from the NW with some mtn wave cloud cover overnight. Will see gusty winds overnight in the normal windy areas but cross barrier flow is only in the 30-35 kt range.

On Mon, WNW flow aloft will remain over the area with additional mid level moisture embedded in the flow. Lapse rates by aftn will be in the 8-9 c/km range with MLCAPE up to 200 j/kg. Overall, expect some widely sct high based showers and isold tstms in the aftn. This activity will produce mainly wind with very little rainfall as lower levels will remain rather dry. Outside of the showers, it will be windy across the higher terrain but speeds will stay below high wind criteria.

Highs on Mon will be much warmer as 850-700 mb temps rise 8-10 degrees from today's levels. This would lead to highs in the 70s across nern CO.

LONG TERM /Monday night through Sunday/
Issued at 221 PM MDT Sun Apr 21 2024

West-northwest flow aloft to prevail Monday night and Tuesday. An upper level low will track southeast across the Northern Plains staying well northeast Colorado. A cold front associated with this system pushes south through eastern Colorado Monday night. This will usher in cooler temperatures for Tuesday. Expect some stratus clouds Tuesday morning, which will slow warming. Highs look to be in the upper 50s to lower 60s Tuesday. Scattered showers and few thunderstorms will be possible over the higher terrain where it will be unstable. A few could survive onto the plains, late Tuesday afternoon and evening. If any convection makes it onto the plains, it is expected to be weak.

Temperatures warm back up for Wednesday as an upper level ridge moves over the state. Highs are expected to reach the mid to upper 70s over northeast Colorado. Can't rule out a stray shower or storm over far northern Colorado Wednesday afternoon/evening.
However, overall dry and warm conditions are expected. The warm temperatures are expected to continue into Thursday as the ridge shifts east of Colorado. On the heels of the ridge will be a quick moving upper level trough. This will bring a better chance for showers and thunderstorms Thursday and Thursday night.

Weak ridging will replace the trough for Friday, though models are hinting there may be enough moisture embedded in the westerly flow aloft to produce rain/snow showers over the mountains. Models also hinting at a few showers late in the day across the lower elevations, though any activity should be weak.

For next weekend, a large upper level low/trough will be across the western half of the country. With this system nearly a week away, not surprising there are differences on the timing, placement, and strength. Good chance temperatures will trend cooler. Precipitation amounts (1-2 inches) are possible if this system takes the right track. This system looks to be warmer, which should keep precipitation mostly to all rain across the lower elevations.

AVIATION /00Z TAFS through 00Z Monday/
Issued at 528 PM MDT Sun Apr 21 2024

VFR conditions will prevail for all terminals through the TAF period. Expect increasing high clouds this evening at/above FL180, persisting through the forecast period.

Current southeast winds should turn to southerly drainage within the next 1-3 hours for KDEN/KAPA, with sustained speeds likely remaining above 10 kts and with occasional gusts near 20 kts possible in the evening before relaxing some during the early morning hours.

Winds will shift more southwesterly Monday morning, before transitioning to WNW flow near midday. Afternoon gusts should exceed 20-25 kts for all areas. SCT-BKN mid-level clouds at/above 080 appear likely, along with isolated high-based showers/virga over the low elevations in the afternoon. Precipitation isn't favored, but virga could produce brief higher gusts closer to 30 kts at times.

Issued at 221 PM MDT Sun Apr 21 2024

Elevated fire conditions will be in place over southern Lincoln county Monday afternoon due to low humidity and gusty west to southwest winds.
