Apex Weather

St. John Valley weather for May 6-12, 2020

Short-Term Outlook: Wednesday – Friday

High pressure will build across the Valley today producing partly cloudy to mostly clear skies and light northwest winds across the region.

Highs will still be several degrees below normal today and tonight as anomalously cool air aloft continues to circulate across the region. An offshore low-pressure area will track northeast later today and tonight and may affect portions of the Downeast coast; however, Valley residents are not expected to see any impact from this system. Overnight lows will drop near-to-below freezing for most locations tonight. Partly sunny skies develop Friday as some moisture works its way into to region as a dissipating frontal boundary moves east towards the region. Another offshore low-pressure area will consolidate and track northeast from the Middle Atlantic region later Friday and strengthen as it moves into the Canadian Maritimes Friday night into Saturday producing increased winds and a rain/snow mixture across the SJV.

Today and tonight

Partly cloudy with a high in the low 50s. Northwest winds 5 to 10 mph. 

Tonight, mostly clear to partly cloudy with a low in the low 30s. Northwest winds 0 to 5 mph.

Thursday, May 7

Partly sunny with a 20 percent chance for precipitation. High in the mid-50s with north winds 0 to 5 mph.

Precipitation tapers off Sunday with mostly cloudy skies across the Valley. Partly sunny skies develop Monday as high pressure builds in from the northwest bringing drier conditions to the region.
