Discussion: A meridional but progressive upper jet pattern is expected this week. Height anomalies indicate back-and-forth positive and negative as thin and quick moving troughs and ridges try to establish with a cut-off upper level low or two. At the
Discussion: A zonal upper jet and positive geopotential height anomalies should dominate the weekend. At the surface that means mild temperatures without disturbance. Friday and Saturday looks the mildest as flow starts out of the S/SW and rocks to W/NW.
Discussion: Sunday night’s cold front was on the front of the trough that we (and most of the Mid-Atlantic/Northeast US) are now underneath. This means low geopotential heights and a condensed cooler lower atmosphere. Today, an upper level disturbance moved
Discussion: The upper jet will be dipping S of NJ from tonight through about Thursday morning. This will allow below average 500mb geopotential height anomalies to build over NJ in said period. At the surface this means a much colder
Discussion: When I was younger, before I studied the science of meteorology, I would falsely associate prolonged wind events in the months of spring and fall. I thought these events, for said periods, were the seasons blowing in and out.
Discussion: Current rain is associated with an unorganized area of frontal precipitation stemming ultimately from Tropical Storm Eta departing the coastal SE US area. This should all move out by noon, at the latest, on Friday with high pressure establishing
Discussion: A strong E US ridge should continue to dominate the pattern through Wednesday morning. This obviously keeps the 250mb jet to the N of NJ with warm/mild high pressure-driven surface conditions beneath. The high pressure that brought us beautiful
Discussion: The 250mb jet should remain well to the N of NJ this weekend and part of next week. A 500mb ridge and surface area of high pressure will correlate with this at the levels beneath. This means mild temperatures
Discussion: A meridional dip in the upper jet will dominate the region with a colder pattern from Sunday night (tonight) through Tuesday. We might be looking at the coldest shot of air yet this season. But first let’s talk about
Discussion: Two dips in the jet (troughs) should push through NJ in the near future. One Friday and another Monday-Tuesday. Said days will therefore feel noticeably colder. Between the dips should be some moderation for Saturday and Sunday but still
