Area Forecast Discussion
National Weather Service Flagstaff AZ
210 AM MST Wed May 8 2024

.SYNOPSIS...Below normal temperatures will continue through the
end of the week, with near/above afternoon highs returning over
the weekend. Typical spring-like breezy will remain through the
forecast period, with slight chances for precipitation across some
areas Friday through Sunday.

.DISCUSSION...A zonal flow will be present aloft thanks to a
elongated low remaining over the Northern Plains. This pattern
will slowly increase our temperatures through the end of the week,
but the majority of our CWA will have afternoon highs staying a
few degrees below-normal for this time of year. Winds will revert
to seasonal breezes for the next few days too.

Model guidance (ECMWF, GFS, NAM) is slowly beginning to agree on a
closed low forming off the backside of this elongated low by
Friday. Although impacts are currently forecast to be minimal with
this set-up, there will be an increase in moisture over Arizona.
There is higher confidence that this moisture will present itself
as cloud cover, but slight precipitation chances are not out of
the question. If showers do become more likely, best chances
appear to be along our Utah and New Mexico border. Wind speeds
are forecast to increase, but look to remain well below any
advisory thresholds.

By the weekend, a ridge is expected to form on-top of this
incoming closed low, creating a Rex Block pattern. This synoptic
pattern will assist with increasing temperatures through the
beginning of next week, where daytime highs should return to
above-normal. There is still uncertainty with how these synoptic
patterns will ultimately shake out, so check back for updates.
