FTB 06-29-2020: Critical Fire Weather & Windy Conditions

Issue Date: Monday, June 29th, 2020
Issue Time: 9:10AM MDT

— Flooding is NOT expected today

The strong Low pressure system has migrated into Idaho, and the jet that’s rotating around base of the trough will move east into Colorado throughout the day. This southwest flow will pull in a fairly dry air mass over the state, and it will help to mix out the majority of the residual surface moisture. Increased surface winds are also forecast across the state with the jet overhead and a developing lee trough, which will elevate fire danger (pink dotted line). So other than some weak, high-based showers over the northwest corner of the state, it should remain dry, hot, and windy. A cold front begins to move into the state from the west later this evening, so expect southwest winds to shift to the northeast as the front passes. There may be some weak showers over the mountains this evening/overnight associated with front, but more stratiform clouds are forecast than wetting rainfall. Like everyone else, I’m looking forward to those cooler temperatures tomorrow. Flooding is not forecast today.

Today’s Flood Threat Map

For more information on today’s flood threat, see the map below. If there is a threat, hover over the threat areas for more details, and click on burn areas to learn more about them. For Zone-Specific forecasts, scroll below the threat map.

Zone-Specific Forecasts:

Central Mountains, San Juan Mountains, Northern Mountains, Northwest Slope, Grand Valley, San Luis Valley, & Southwest Slope:

A couple high-based storms will be possible this afternoon over the northwest corner of the state as mid-level energy mixes with some residual moisture. Overall, the dew point depression will be large, so only light rainfall and sprinkles are forecast from the storms. The main threat will be gusty outflow winds on top of already higher winds. Additional weak showers may be possible along the front overnight, but flooding is not forecast. Tune into your local NWS office for the latest on Red Flag Warnings that have been issued.

Primetime: 2PM to 5AM

Southeast Mountains, Front Range, Urban Corridor, Southeast Plains, Northeast Plains, Palmer Ridge, & Raton Ridge:

It’s going to be a hot one with highs forecast to reach the mid to upper 90Fs along the I-25 corridor. Highs will likely reach the triple digits over the far eastern plains. It will be windy this afternoon with a developing lee trough, so tune into your local NWS office for the latest on Red Flag Warnings that have been issued. It’ll be too dry for afternoon rainfall, but expect an increase in cloud cover this afternoon to help with the heat.
