Cold Possibly Wintry Week Expected (Jan 18-22)

Temperatures should crash overnight as an Arctic front passes through the region. This will set the stage for a cold week ahead of a possible late-week winter storm. Let’s break it down.

Monday (Jan 18) high temperatures should be held in the 20s statewide. Skies should be partly sunny. Winds should breezy to gusty out of the W/NW. Wind chills should be rough. Overnight lows should fall into the single digits for NNJ elevations and teens for the rest of New Jersey.

Tuesday (Jan 19) high temperatures should again be held in the 20s statewide. Skies should be mostly sunny. Winds should breezy to gusty out of the W/NW. Wind chills should again be rough. Overnight lows should fall into the teens for NNJ elevations and lower-20s for the rest of New Jersey.

Wednesday (Jan 20) high temperatures should reach the low-to-mid 30s. Skies should be partly cloudy to mostly cloudy. Light snow showers are possible evening through overnight hours. Winds should be light out of the NW. Overnight lows should drop into the teens for NNJ elevations and 20s for the rest of New Jersey.

Thursday (Jan 21) high temperatures should range from lower-30s in NNJ elevations to upper-30s for the rest of New Jersey. Skies should be mostly sunny. Winds should be light out of the NW. Overnight lows should drop into the teens for NNJ elevations and 20s for the rest of New Jersey (maybe 30 along the SNJ coast).

Friday (Jan 22) and into the weekend is a bit uncertain for now. All major models are showing a possible major winter snow storm which would mean heavy snow for most (possible mid-storm changeover issues at the coast) and heavy direction-changing winds surrounding a passing low pressure system. If model guidance holds this scenario through 12Z guidance tomorrow then I will make a video tomorrow evening explaining my initial thoughts. I’ve tested my video podcast setup and I think I’m ready to rock with it.
