Below are the risk maps for today and tomorrow from the Storm Prediction Center. The maps show a critical to extreme risk for today basically along the eastern slopes of the Rockies with the extreme risk occurring in eastern Colorado, extreme southeastern Wyoming, and extreme northwestern Nebraska. The threat moves tomorrow to include most of Nebraska, southern South Dakota, and parts of eastern Wyoming though no extreme threat is indicated at this time.

The fire risk is being helped out by a lack of moisture over these areas this month as shown below. Most areas inside this risk for wildfires have seen less than 50% of the typical amount of precipitation they would normally see over this time period with some areas even seeing less than 5% of the typical amount of precipitation they would normally see over the past 30 days!
Coupled with this lack of moisture, strong southerly surface winds will aid the problem today and tonight bringing warm and dry air in as depicted by the NAM model below. Sustained wind speeds in excess of 20 knots will be in place across much of the northern section of the threat zone today with some areas even seeing sustained winds up to 30 knots. Below this is an image showing just how much dry and warm air is being advected into this area, with 850 mb temperatures being above 20 degrees Celsius in most of the wildfire risk area this evening and some areas even seeing this number reach above 25 degrees Celsius. Dew points at the surface (not shown here) will also be well below 30 degrees Fahrenheit for most of the areas to the west of this area of 25 degree Celsius or greater 850 mb temperature, showing just how dry this air is.
Tomorrow the cold front will push through switching the winds to a more northwesterly direction but they will still be quite strong for some, especially across the southern South Dakota portion of the threat area as depicted below by the NAM model.
Wind gusts will be even higher across these areas today and tomorrow prompting the issuance of High Wind Warnings across much of the northern High Plains. There have already been numerous reports of small fires across the threat area for today. Luckily, a couple storm systems should bring some chances at rain over the next week for this area, which will hopefully cut down on any long term problems this area may experience this spring due to wildfires.
