— Flooding is NOT<\/strong> expected today<\/em><\/p>\n

The 500mb high will continue to spin over NM today, which will keep the subtropical moisture to our south once again. Similar to the last couple of days, this will keep flow aloft west\/west southwest flow and continue to entrain a drier air mass, which should keep the chance of storms low again this afternoon. A couple of shortwaves are marked in the water vapor imagery below associated with the trough<\/span> that is moving over the west coast. While this may aid in a slight moisture increase, the storms that form with convergence over the Palmer\/Cheyenne Ridges and extra lift from the shortwaves will likely produce some gusty winds due to the lack of low-level moisture. The shortwave<\/span> over Utah is expected to help increase the upper-level clouds over the Urban Corridor, Palmer Ridge and Northeast Plains this afternoon and overnight. Over the Southeast Plains, weak convergence may spark a couple of isolated<\/span> thunderstorms. With dew points<\/span> below 50F, these storms will likely produce some spotty rainfall with gusty winds.<\/p>\n

\"\"<\/a><\/p>\n

This afternoon stronger upper-level winds will set up along the CO\/WY boarder, which will bring back the chances for some gusty winds to mix down to the surface. Low relative humidity and stronger winds will bring back critical fire weather<\/span> to the northern half of the state. A Red Flag<\/span> Warning<\/span> has been issued for the Grand Valley, Northwest Slope and Northern Mountains through 9PM tonight. As anticipated, there is no flood threat forecast for Thursday.<\/p>\n

\"\"<\/a><\/p>\n

Zone-Specific Forecasts:<\/strong><\/h3>\n

Southeast Plains, Raton Ridge, Southeast Mountains, Front Range, Palmer Ridge, Urban Corridor, Northeast Plains:<\/strong><\/h4>\n

Lack of low-level moisture and downsloping<\/span> winds will limit the chances for rainfall this afternoon. Storms that are able to fire will be high-based once again and produce some gusty winds. The shortwave<\/span> currently moving through Utah will reach the Urban Corridor, Front Range, Palmer Ridge and Northeast Plains by this afternoon. While not much rainfall is expected, there should be enough of an increase in moisture that cloud cover will be on the rise. Max 1-hr rain rates are expected to be 0.05 inches or less. Some isolated<\/span> storms are also possible over the southern Southeast Plains with max 1-hour rain rates up to 0.1 inches. Flooding is not expected today.<\/p>\n

Primetime: 3PM – 8PM<\/p>\n

Grand Valley, Central Mountains, San Juan Mountains, San Luis Valley, Southwest Slope, Northern Mountains, Northwest Slope:<\/strong><\/h4>\n

A tight gradient near the CO\/WY border is expected to mix down some strong winds this afternoon. Gusts between 25-35 mph are forecast. With dry air entrainment from the west and rising high temperatures, relative humidity values are expected to drop into the teens. This means critical fire weather<\/span> will return to the Grand Valley, Northwest Slope and Northern Mountains through this evening. The lack of low-level moisture will again nearly zero out the chances for rainfall over western Colorado. Upper-level cloud cover is expected to increase with the passing shortwaves, so low temperatures tonight may be a couple of degrees higher than they otherwise would be.
