.DISCUSSION...

Issued at 400 PM CDT Mon May 12 2025



Hot, dry, and windy conditions continue this evening, with

humidity near to below 25% through sunset. No changes to the 

today's red flag warning.



A repeat of Monday is expected on Tuesday as we'll see a rather

sharp upwards climb in temperatures through the morning. Dew

points may rise a few degrees higher, but temperatures may once

again rise towards the 90 degree mark. Winds today have again

reached past the forecast, and while soundings suggest a

slightly weaker wind aloft, still see enough potential for

critical conditions that a fire weather watch was issued for most

of the area Tuesday. 



On Wednesday, very warm temperatures near record levels are 

expected, but dew points will again rise further, leading to RH 

values bottoming out near 30%. An increasing surface pressure 

gradient and increasing southerly low level wind can be misleading

as forecast wind gusts near 30 mph have the potential to rise a 

bit further than forecast.



High chance of a wetting rain with showers and storms Wednesday 

night through Thursday means reduced fire danger and greener 

fuels late week.



People are urged to exercise extreme care with respect to outdoor 

activities that could cause grass fires. Report new fires quickly to

the nearest fire department or law enforcement office.
