Wednesday June 30, 2021 Forecast First

Weather

Another Flood Watch for the Grizzly Creek burn scar is in effect on Wednesday June 30, 2021.

The Storm Team anticipates more showers and thunderstorms to develop late this afternoon and continue into the late evening hours. The High Country will have better storm chances and as a result Pitkin, Eagle, and portions of Rio Blanco and Garfield Counties are under a Flood Watch until 9 pm. Specifically the Flood Watch in eastern Garfield county is for the Grizzly Creek burn scar. If an upgrade to a Flood Warning occurs, CDOT should initiate another temporary safety closure for I-70.

For Wednesday night, the lower elevations/western locations will be looking at storms developing over the mountains, mesas and plateaus with some valley drift through 11 pm. A partly cloudy finish with near normal lows Thursday morning are in the forecast. The overall weather pattern for later this week and into the long holiday weekend will hold slowly diminishing showers and thunderstorms. This does not eliminate storms from the forecast, but daily high temperatures will slowly rise as the storm chances start to wind down. The flow becomes more westerly this weekend which will not support the summer thunderstorm pattern we have been experiencing of late (NAM). This westerly flow however will inject drier air and allow for hotter temperatures. The heat and the mountains will be the main lifting mechanisms to get storms going. A return to the daily late pop-up storms is expected with a lot more sunshine. Gusty winds and lightning will become the new focus for storms developing for the next 5 days, flooding and debris/mud flows will still need to be monitored.
