.SYNOPSIS...Isolated showers will end in northeast Arizona
overnight, with fair weather elsewhere. Expect dry and warmer
weather this coming week, with increased southwesterly breezes.
&&
.DISCUSSION...Today...An upper-level low currently situated over
Kingman will slowly move eastward through the day as it begins to
lift and weaken. With abundant sub-tropical moisture still in
place, along with the large-scale dynamics from the low, scattered
to numerous showers and thunderstorms have begun to develop
across northern Arizona. This trend is expected to continue
through the afternoon and into the early evening hours.
Given the increased moisture leading to very heavy rainfall rates,
flash flooding will remain the primary concern going into the
afternoon. However, faster storm motions around 15-20 kts will limit
the residency time of any given storm. Thus, the most likely areas
to see flash flooding will be areas that see training storms or rain
sensitive areas (i.e. slot canyons and burn scars).
Monday through Saturday...As the trough departs the region, warmer
temperatures and mainly dry conditions look to return. A couple of
showers near the White Mountains can not be totally ruled out on
Monday, but the vast majority of the area will remain dry.
A weak trough looks to brush just to the north of Arizona on
Tuesday, this will likely only bring some slightly breezier afternoon
winds and high clouds. A brief sprinkle or two will be possible
mainly around the Kaibab Plateau, but otherwise dry conditions look
to prevail.
Heights continue to rise through the middle of the week as high
pressure builds to the south and east. Dry conditions and warming
temperatures look to continue as a result. Near the end of the week,
a trough looks to move into the Great Basin, however the only
impacts to this look to once again be breezier winds and a slight
dip in temperatures by the weekend.
