Area Forecast Discussion
National Weather Service Flagstaff AZ
119 PM MST Fri Jun 14 2024

.SYNOPSIS...A brief warming trend will take place between today
and tomorrow, along with isolated showers/thunderstorms near NE AZ
this afternoon/evening. A dry, long-wave trough will bring cooler
temperatures and gusty winds Sunday through the beginning of next
week. Warm and calmer conditions look to return by mid to late
week.

.DISCUSSION...A quick moving disturbance brought isolated to
scattered showers and thunderstorms today, primarily in
central/northern Apache/Navajo Counties. Hi- res guidance
continues to indicate convective activity towards the Four
Corners through 5 PM MST this evening.

A brief warm- up will take place on Saturday, as a weak ridge
settles over the region, prior to a long-wave trough pushing down
from the Pacific Northwest. This low-pressure system will bring
gusty winds, cooler temperatures, and mostly dry conditions
starting Sunday. Wind gusts are shaping up to be 30-40 mph Sunday
and Monday afternoon, but peak wind gusts will be on Monday.
Currently, Sunday looks to hold widespread, single-digit relative
humidity values that slightly climb to low-mid teens on Monday.
With the drier pattern and strong winds, near-critical to critical
fire weather concerns are possible both days. No products have
been issued at this time, but stayed tuned for updates.

Wednesday Onward...The previously mentioned trough will gradually
weaken through the end of the week and a subtropical high will
begin to build up over our area. As a result, temperatures will
increase through the end of the week and winds will become
lighter. Look for daytime highs 2-10 degree above normal Thursday
and Friday. It looks like enough moisture will funnel in across
eastern Arizona toward the end of next week, bringing our
precipitation chances between 10-20% for our AZ/NM border. There
is still time to hash out all those details, so check back later.
