...COLD TEMPERATURES WITH AFTERNOON SHOWERS AND BREEZY WESTERLY WINDS...
...LOW CHANCE OF AN AFTERNOON THUNDERSTORM TODAY AND TOMORROW...

.DISCUSSION...
An upper level trough will continue to deepen to our north,
bringing cold temperatures, breezy winds, and intermittent
afternoon snow showers to the burn area through Wednesday evening.
Showers look to begin today around 3pm, with precipitation likely
being snow/ice pellets due to the colder air aloft. Minimal
accumulations are anticipated, although locally heavier amounts
are possible in stronger showers. Expect breezy afternoon westerly
winds winds each day, with the strongest winds later today from 2
to 6pm. Locally higher gusts are possible outside of showers.
Weak instability will provide the potential for a stray
thunderstorm this afternoon and Wednesday afternoon, although
confidence is low (15% chance).
