Apex Weather

St. John Valley weather for April 1-7, 2020

Short-Term Outlook: Wednesday – Friday
An upper-level low will be blocked over the region today into Thursday thanks to a strong North Atlantic high pressure ridge to the east.

The North Atlantic high will break down at the end of the week allowing high pressure from the west to build in with drier conditions by Friday and decreasing clouds Friday night. Enough moisture will be channeled into the region from the north/northeast to allow for intermittent rain over the course of the day today mixing with snow in the morning and during the overnight hours tonight. Rain is expected through the day Thursday before tapering to rain showers Thursday night. Drier air begins to move in, through with plenty of moisture aloft keeping skies mostly cloudy Friday before high pressure to the west builds further east and reduces moisture overhead Friday night into Saturday. Based on current data, light rainfall and slow snow melt should avoid any flooding issues with area rivers, streams, and lakes.

Today & Tonight
Cloudy with a 100% chance for rain, mixing with snow in the morning at times. Between 0.10 and 0.20-inch precipitation expected. High in the upper 30s with northeast winds becoming north near 5 mph.

Overnight, rain/snow likely with a 100% chance for precipitation with liquid totals between 0.20 and 0.25-inch anticipated. Low in the lower 30s with north winds near 5 mph becoming northeast 5 to 10 mph after midnight.

Thursday, April 2
Cloudy with a 100% chance for rain. Between 0.20 and 0.25-inch expected by evening. High in the low 40s with northeast winds 10 to 15 mph.

Friday, April 3

Friday night, partly cloudy with a low in the middle 20s. Northeast winds 0 to 7 mph.

Further Ahead: Saturday – Tuesday
