National Weather Service Great Falls MT
204 PM MDT Mon Apr 22 2019

.SYNOPSIS...

Clear and Dry conditions will persist through Tuesday with
temperatures gradually increasing through Wednesday. Gusty winds
have started to pick up along the Northern Rocky Mountain Front
and adjacent plains. Tuesday into Wednesday, there is a chance of
some light showers to track through Central Montana, with warm
temperatures continuing into Wednesday. The next weather producer
moves into the area on Friday expect showers and possible
thunderstorms.

.DISCUSSION...
Monday through Thursday...The warm and dry trend will continue
through the later half of the week, with the potential for showers
to develop over Central Montana for Tuesday and Wednesday.
Stronger cross-barrier flow will keep the drier and warmer
conditions along the mountains and adjacent plains, but continue
to increase gusty westerly winds over the area through Wednesday.
However, the zonal upper level flow will advect some moisture
into the area, allowing to potential for shower development
through Thursday. -TP

Friday through Monday...The next weather producer moves into The
Treasure State on Friday. The weekend ahead looks to be cool and wet
with a possibility of seeing snowfall even at lower elevations. We
are working to clarify the details of this event as it approaches,
and we will continue to communicate as necessary.

.AVIATION...
Updated 1125 AM MDT Mon Apr 22 2019

Ridging continues to dominates the area through the TAF period, with
VFR and some breezy conditions expected around most terminals
through Tuesday. Westerly cross-barrier flow with a tightening
height gradient sets up across north and central Montana. Expect
drier conditions along with gusty winds to develop today, causing
some turbulence near mountains, particularly along The Northern
Rocky Mountain Front. -TP/JF

.HYDROLOGY...
A small stream flood advisory remains in effect for the central and
northern portions of Meagher County. Recent rainfall and snowmelt
continue to allow for the North Fork of the Smith River to exceed
bankful on the north side of the city of White Sulphur Springs.
Additional minor flooding from small streams is possible over the
northern portions of the county. Thus the flood advisory will
continue until further notice.
