Discussion: We’ll spend much of this week to the S of the upper-jet (in a ridge). Only the nose of a progressive trough should then swing through between Friday night and Sunday morning before ridging returns for next week. With
Discussion: The positive axis trough pattern is about to end for the E US. It’s been relentlessly holding us slightly below average in temperature and in some cases (like last night/today) well below average. The 250mb jet should make its
Discussion: We’ve had a nice run of non-disruptive weather conditions. Tomorrow (Wednesday) that will likely come to an end with a stormy frontal passage. Low pressure will track through PA into New England (just to the NW of NJ) on
Discussion: The upper level pattern of repeating positive-axis troughs, swinging from central Canada through the E US, will continue this week. Tuesday looks like the mildest day of the week from SW flow culmination ahead of the cold front. Wednesday
Discussion: Lower 500mb heights should continue to dominate the pattern with trough after trough swinging down and in from central Canada through the US. Because the troughs feature a positive axis, nothing big can really spin up. It does however
Discussion: The upper levels this week have a very unsettled look. 500mb geopotential height anomalies should alternate between near-average to below-average. This means a lower general atmosphere (cooler aloft) which allows milder rising air and moisture (from higher-angle diurnal surface
Discussion: Not a lot going on this week. Monday through Thursday fall under the front side of a ridge. This should allow most locations to near-70 during the day and stay above 40 at night. Friday then looks a little
Discussion: High pressure to our W (over S IL/W KY) is currently producing cold NE quadrant anti-cyclonic flow over NJ. This is tapping colder Canadian air mass and giving us some wind to make it feel even colder in the
Discussion: The upper-jet looks very wavy and meridional over the next week or so. The lows are obviously not dipping as far S anymore as our p-types have been mostly rain and driven by cold frontal passages to the S
Discussion: Most of our pattern, this weekend into next week, will be heavily influenced by a few low pressure systems passing to our far NW. There’s one right now dragging a mostly-dry cold front through. Today, we’re experiencing the warm
