Cool and Cloudy (Sept 11-13)
Discussion: The tropics are on fire, as they should be this time of year. There are 4 systems currently being tracked by the National Hurricane Center. Two of them look to remain out to sea (Paulette and Rene – as

Discussion: The upper-jet should stay to the N of NJ this weekend. 500mb geopotential heights should back in from the E/NE and build over the E US—flexing ~Thursday AM before upper-flow becomes more W/NW instead of W/SW. This should produce
It’s time to harness WeatherTrends360 technology and look at how the rest of September 2020 should play out. WeatherTrends360 algorithms are documented with an 84% verification rate and are based on oceanic water cycles, time table series and very complex
Discussion: The upper jet should stay just to the N of NJ through this weekend and into next week before forming a meridional pattern by mid-next week. 500mb analysis indicates average heights until a ridge backs in, off the Atlantic
Discussion: Upper-level flow will be heavily influenced by a SE US ridge between Bermuda and the mainland. The N jet should remain zonal but press against the SE US ridge’s N anti-cyclonic flow. The pattern doesn’t hint at becoming meridional
Discussion: The upper-jet looks very flat and zonal this weekend. Upper-level geopotential heights look average to slightly-below average. While boring aloft, the lower-levels/surface conditions should respond as follows. Today we have the leading edge of unsettledness beginning by late-afternoon/early-evening. This
Discussion: Laura is a category 4 (major) hurricane in the Gulf of Mexico heading for a landfall just on the LA side of the TX/LA gulf coast border later this evening. There’s actually a small chance of reaching category 5
Discussion: New Jersey is currently on the W (back) side of a trough that is primarily developing over SE Canada and NE US. A small upper-level disturbance is rounding the back-side of this trough which is enhancing the jet streak
Discussion: Let’s first talk about the setup for NJ before we talk about the tropics. We currently have a progressive trough swinging through the NE US. It’s nose will push through the N Mid-Atlantic US (NJ) on Tuesday which could
Discussion: We have two upper-jets involved in this weekend’s pattern. The southern jet has formed a trough over the general interior SE US. The northern jet is a bit more zonal and should eventually take over as the primary for
