KEY MESSAGES
- LOW CHANCE FOR FIRE WEATHER IMPACTS FRIDAY INTO THIS WEEKEND.
DISCUSSION
ISSUED AT 1252 PM CDT TUE APR 28 2026
..SYNOPSIS
SURFACE ANALYSIS THIS AFTERNOON SHOWS A SURFACE LOW WORKING ITS
WAY AWAY FROM OUR AREA, DIMINISHING THE PRESSURE GRADIENT AND
THUS ALLOWING FOR WINDS TO DIMINISH. AFTERNOON CUMULUS HAS
DEVELOPED BUT WILL REMAIN BENIGN AS DEWPOINTS REMAIN FAIRLY DRY.
THIS WILL DIMINISH AFTER SUNSET WITH WINDS BECOMING MORE LIGHT
AND VARIABLE.
THE REMAINDER OF THE WEEK WILL BE MOSTLY RINSE AND REPEAT WITH
TEMPERATURES IN THE 40S AND 50S WITH GENERALLY LIGHT WINDS AND
DRY CONDITIONS. TEMPERATURES LOOK TO INCREASE THIS WEEKEND,
WHICH SHOULD CAUSE RELATIVE HUMIDITY VALUES TO BECOME LOWER.
HOWEVER, THERE IS NO STRONG SIGNAL FOR WIND AND GREEN UP IS
ONGOING, SO THE PROBABILITY FOR CRITICAL FIRE CONDITIONS IS LOW.
HAVING SAID THAT, NEAR CRITICAL FIRE WEATHER CONDITIONS MAY
ARISE WITH MINIMUM RH VALUES AROUND 20%, EVEN WITHOUT WIND.
REGARDLESS, THIS REMAINS THE ONLY WEATHER IMPACT FOR THE
FORECAST PERIOD.
