Heavy Precipitation Outlook
Flash Flood Prediction Program

DRY AND GUSTY CONDITIONS TODAY AHEAD OF COOL FRONT OVERNIGHT
-Today will be hot, very dry, and sunny with gusty conditions across The District. Upper level ridging and lack of moisture will inhibit convection in the area today and tonight.
-Clear skies and 700mb thermal ridging along the plains will produce high temperatures in the upper 80's to low 90's across The District. Dew points will drop into the 20's this afternoon, resulting in relative humidities in the teens. A fire weather watch has been issued for northeast Colorado.
-Winds are expected to increase ahead of tonight's cool front with wind gusts reaching 20 mph. Cloud cover will also increase ahead of the frontal passage, but no precipitation is expected in The District overnight.
STORM RAINFALL POTENTIAL AND DURATION: No precipitation is expected today or this evening.

A LOOK AHEAD: A dip in the upper level jet will pass over northern Colorado overnight, dragging a weak cool front across the plains. This front will bring slightly cooler temperatures to the area, lowering Friday's high temperature to the mid 70's. While no precipitation across the District is expected at this time, a small moisture increase on Friday will reduce fire weather conditions across the state. Ridging over the Desert Southwest will continue this weekend, bringing warm and dry conditions to the plains once again.
