KEY MESSAGES

- Dry weather will prevail over the next several days with temperatures near seasonable.

- A weak system may bring light precipitation by Friday night or Saturday.

DISCUSSION

Clear skies and light winds are expected tonight. This may allow patchy fog to develop again, mainly in the river valleys. Low will be 20s to low 30s.

The upper ridge impacting the region will linger into Thursday before an upper trough pushes in Friday. A weak cold front moves in Friday night with a breezy day expected for Saturday. There may be isolated showers around but models are not in agreement with placement and/or timing yet. This front should help to mix the atmosphere and warm temps above normal starting Friday.

An upper ridge returns late in the weekend for dry and continued mild conditions.

FORECAST CONFIDENCE & DEVIATIONS:

No major changes were made to the forecast package this afternoon. There is some low to moderate confidence of fog overnight tonight into Wednesday morning again. Otherwise, expect high confidence in the mostly dry and warmer conditions through the week and low confidence in precipitation over the coming weekend.
