KEY MESSAGES

- Expect isolated rain showers this afternoon, perhaps a low probability of a stray thunderstorm.

- Much warmer weather conditions are expected for the end of the week.

- Unsettled weather may yet again emerge this weekend with shower chances returning to the forecast.

DISCUSSION

WEATHER PATTERN OVERVIEW:

The region remains under the influence of a large upper trough, while surface high will keep precipitation chances mainly confined to the southwestern portions of the CWA.

Meanwhile, as the trough translates east, an upper ridge pattern looks to become more pronounced across the western CONUS. This will ensure dry conditions and much warmer temperatures toward the end of the week.

Ensemble solutions tend to show more spread toward the weekend, though early suggestions are that a return to active weather is a potential, along with a continuation of seasonably mild temperatures. That ridge may begin to break down while a shortwave tracks through the northwest upper flow parked over the region.

FORECAST CONFIDENCE & DEVIATIONS:

Pops were adjusted for the near term to reflect existing observations, while near term winds were nudged a bit above NBM.

Confidence is above average that weather will remain cool and mostly dry with isolated showers in the southwest at times. There is also decent consensus for warmer temperatures through Friday, with growing uncertainty over the weekend.
