.DISCUSSION...

WEATHER PATTERN OVERVIEW:

A disturbance moving northeast out of ID will bring showers and
isolated thunderstorms through mainly Friday evening. Northeast of
Whitewater to Sidney line stand to receive very little if any
rainfall from this system. Greatest amounts will be near and south
of a Jordan line with amounts of a third to a half an inch a good
possibility.

The disturbance will then drift to our south Saturday and toward
the central Plains next week. An upper trough will move through
the Pacific NW Monday but lift up into Canada next week, leaving
northeast Montana mainly dry. Chances for rainfall for the
remainder of the period look slim as an upper ridge tries to build
in over the area. This will eventually allow temperatures to warm
to above normal levels by the middle or the later portion of next
week with dry conditions.

.AVIATION...

A round of showers and MVFR ceilings will move into the TAF site
late tonight and Friday. Better conditions are expected at KSDY
but low ceilings elsewhere are expected to continue into Saturday.

East to SE winds of 10-20 kts will continue through Friday.
