Area Forecast Discussion
National Weather Service Flagstaff AZ
331 AM MST Thu May 23 2024

.SYNOPSIS...A dry and breezy weather pattern will remain in place
across northern Arizona through Saturday, with the strongest winds
and potential for critical fire weather conditions on Friday. By
Sunday and into next week, high pressure will bring lighter winds
and a noticeable warming trend.

&&

.DISCUSSION...A broad trough of low pressure remains over the
western United States, with the bulk of the trough residing to our
north. This pattern will remain in place through Saturday, with a
few s/wvs increasing our daytime winds, especially on Friday. The
entire pattern becomes more progressive by Sunday and into next
week, with rebounding hghts and decreased winds as the gradients
weaken.

Southwest winds on Friday will likely just reach, or even exceed
Wind Advisory Criteria over parts of the LCR. However, widespread
Wind Advisory conditions are not expected. In addition, very low
afternoon relative humidity values will make for near Critical Fire
Weather conditions, although fuels remain suspect. For now, we will
hold off any headlines for Friday, but we are right around the 50
percent decision threshold for now. Thursday and Saturday feature
similar conditions, but wind speeds will not be as strong.

Higher hghts for next week will bring a warming trend, reaching
above normal by next Tuesday or Wednesday.

There is no precipitation in sight.
