Fire Weather Forecast for Northeast and North Central Colorado
National Weather Service Denver/Boulder CO
247 PM MDT Wed May 24 2017

.DISCUSSION...Tonight and Thursday...
Warm and dry tonight and the west winds should diminish later
this evening. Tomorrow the Plains should see a wind shift to the
east-northeast with gusts 20-25 mph and higher RH and slightly
cooler air behind the front. Thunderstorms are possible early
afternoon in the mountains and across the Plains after about 2 PM.
Frequent lightning and gusty winds are likely with any storms that
develop, with the best chances across the northern third of
Colorado. Snow levels will remain above 11.5kft Thursday
afternoon.

LONG TERM DISCUSSION...Thursday night through Monday...
It will be unsettled and cool Thursday evening through Saturday
with mainly afternoon and evening showers and thunderstorms.
Saturday will be the coolest day as an upper level system passes
over the state. This will also likely bring showers and scattered
thunderstorms. It will warm Sunday and Monday as high pressure
builds over the Great Basin. There should be enough moisture and
instability for isolated showers and thunderstorms each afternoon.
