Discussion:

.SHORT TERM…
Weak north flow will be over the region tonight as the upper low resides over the SE corner of the state. Convective rain showers will persist thru the first part of the night, mostly becoming dry after midnight with a stray shower or two potentially hanging around. Additional rain totals will be varied as is the case under scattered activity. Dew points are progged in the mid 30s with skies becoming mostly clear after midnight. Surface winds will be N/NW and calm to light. Based on temps aloft alone the potential overnight low looks to be around 30 degrees. The active weather and elevated dew points however will keep most in the upper 30s to low 40s with the cold spots reaching mid 30s. Protections are not anticipated to be needed.

As the upper low ejects to the SE an upper ridge will begin moving in bringing a stretch of dry and fair weather with temps aloft warming. Dew points are progged in the mid 30s under mostly sunny skies. Upper energy passing thru from the west looks to bring a mid level cloud shield over the districts overnight with mostly cloudy skies anticipated, weather is expected to remain dry however. Winds will be SW and light, becoming more variable and calm to light overnight. Temps aloft indicate a potential overnight low temperature in the mid 30s. Observed lows will be warm with the cloud cover and reside mostly in the mid to upper 40s.

.3-5 DAY…
Upper ridging will continue to move into the region Monday under NW flow. Flow will turn SW by Wednesday as the ridge progresses east. Weather will be dry and fair aside from some breezy and gusty afternoon winds, especially Monday. Temperatures will continue to be warm with a slight cool down in temps aloft for Monday night as an upper feature moving into B.C. from the west flattens the ridge. This upper feature will also tighten gradients enough that NW wind gusts around 40 mph will be possible Monday afternoon. Based on temps aloft however the potential overnight low looks to be around 33-34 degrees Monday night, and warmer Tuesday and Wednesday nights. With winds remaining generally light Monday night along with dew points progged in the mid 30s, most will observe lows in the low to mid 40s Monday night. Frost risk will be minimal for the period.
