.DISCUSSION...

Evening Update:

Given the near saturated near surface environment and persistent
low stratus and rain showers, have added patchy fog across the CWA
tonight. Other forecast elements remain on track for now with
little other change made at this time.

Previous Discussion:

Expected thick and wide band of moderate rainfall is now sweeping
northward through our area, accumulating around 0.25 inch. It
seems we have waited a long time for a rain like this. Feel good.
Dry slot has already encroached into this rain by cutting of the
precip in our southern zones.

As the afternoon and evening continues, the organized banded
nature of this storm will begin to take on a more scattered, hit-
and-miss nature, therefore less confidence in precip timing and
amounts.

The responsible upper-level low pressure system is stalled over
western Wyoming and will only slowly move through our region
through Monday.

Models are indicating that these scattered rain showers will be
possible tonight through Tuesday morning. The overall system
circulation is more evident in the higher resolution hourly precip
models.

Tuesday and Wednesday, a dry and warm pattern sets up with NW
flow aloft.

Wednesday night and beyond, a cold front from the Canadian Prairie
will allow a colder air mass to take control over our region.
