SHORT TERM. (This evening through Tuesday) Issued at 250 PM MDT Mon Jun 14 2021
There is not much convective cloudiness over the CWA at this time. There is a bit over northeast Park, southern Jefferson and southwestern Douglas Counties. There is also a bit east of the Denver Metro Area associated with a boundary. Temperatures are in the lower to mid 90s F right now over the plains. Dew points are still in the upper 40s to lower 60s F. Southeasterly winds are covering the eastern 2/3rds of the plains, with variable winds over the western 1/3rd. There is a pretty weak Denver cyclone centered around southwestern Weld County right now.
The upper ridge will stay right over the CWA tonight and Tuesday with very weak flow aloft. There is no synoptic scale energy for the CWA tonight and Tuesday as well. The low level winds will be diurnally driven and pretty weak. Moisture will be sparse tonight and Tuesday. It will remain somewhat capped with the warmth aloft. A couple of the hi-res models show some convection this evening over the far northeast corner so will leave some minor pops there. Will also let minor pops in late Tuesday afternoon for the southwest and south central CWA. Temperatures-wise, it will stay at least 10 degrees F above normals for tonight's lows and Tuesday's highs, at least for the eastern 2/3rds of the CWA.
LONG TERM. (Tuesday night through Monday) Issued at 221 PM MDT Mon Jun 14 2021
The large upper level ridge of high pressure which has dominated the Rocky Mountain Region over the past several days will flatten Wednesday and Thursday as an upper level shortwave moves across the Northern Rockies and Plains States. Hot and dry weather will continue through Thursday with max temperatures in the mid to upper 90s on the plains with some locations possibly reaching the century mark. There may be just enough moisture available to produce a few high based showers and storms across the CWA.
On Friday, models are showing a cold front moving across Northeastern Colorado which should bring some relief to the heat. Some additional moisture behind the front may result in a better chance for storms across the mountains, foothills and adjacent plains. However, forecast sounding suggest most of the plains should be capped and remain on the dry side.
Over the weekend, the upper high is progged to retrograde into the Lower Desert Southwest with a northwest flow aloft over Colorado. This pattern should allow occasional upper level disturbances to move across the area which should result in a better chance for afternoon and evening showers and storms across North Central and Northeastern Colorado. Temperatures should remain slightly above normal values with highs in the upper 80s to lower 90s on the plains.
Early next week, models are hinting at a stronger cold front moving across northeastern Colorado in response to a potent upper shortwave moving across the Northern Rockies. This pattern would result in cooler unsettled weather east of the mountains on Monday.
AVIATION. (For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 221 PM MDT Mon Jun 14 2021
Weak flow continues at DIA this afternoon with mainly an easterly component to it. Southeasterlies are progged by 00Z later this afternoon, then normal drainage patterns by 06Z. There will be no ceiling issues.
HYDROLOGY. Issued at 250 PM MDT Mon Jun 14 2021
There is a slight chance of showers and thunderstorms over the far northeast corner this evening. If there is a storm, it could produce brief heavy rainfall, but flash flooding would still be unlikely.
Isolated to scattered showers and storms will return to the foothills and mountains Wednesday and continue into the weekend. At this time, storms are expected to be isolated and weak, thus keeping the flash flood threat for the burn areas very low.
