Weather

Warmer/drier...ahead of a storm to glance the region late tonight/early THU. Expect a likely marginal area of critical wind/low RH focused mainly southwestern NM later today. Cooler/more stable by FRI/SAT with precipitation focused divide eastward as a weak system traverses the region. An even stronger system next TUE-THU with a potpourri of weather likely.  A dynamic weather pattern continues with an active pattern expected to continue for the foreseeable future. Weak ridging to be broken down as a weather system will glance the region from the north with some precipitation across the northeast and some marginal wind/low RH conditions across the far south. Moist across the east as a backdoor front sinks south-west behind the departing system with another weather system to arrive FRI/SAT with slightly cooler temps., increased RH values, more stable air and likely precipitation focused across the eastern 1/2 of the region. Drier beginning on SUN with a warmup MON/TUE just ahead of another stronger weather system next TUE-THU. Likely areas of critical wind/low RH with this system next TUE/WED with a shot of cooler temps. and precipitation across parts of the north and eastern plains.

Fuels/Fire Potential

Fire potential back to a moderate/High around midweek, then decreasing again late week/weekend. Swings in fire potential will continue to track the changeable weather through the coming weeks. Significant fire activity which does occur will most likely be human-related, and occurring on drier and windier days across low-mid elevation areas where dormant/available fine fuels continue to be a major factor. With that said, conditions are beginning to vary so substantially that we may see as many warm/dry/unstable days as windy ones this spring...and we're seeing signals of dry thunderstorm potential towards the end of the warm/dry periods that could have impact.  A mosaic of new and ongoing green-up is likely to continue, which will generally mitigate and also complicate the contribution of fine herbaceous fuels towards fire potential.
