Premium Weekly Outlook 5/9 – 5/14: More sunshine and warmer temperatures

/by

The omega block pattern that supported that the cool, cloudy wet weather for most of last week, is breaking down. More days with sunshine and warmer temperatures are likely this week, with high pressure or confluence underneath an upper-level low over Southeast Canada, keeping frontal boundary mostly south of the region.  But an -EPO block developing this week may eventually lead some wet weather to return at the end of this week and the start of next weekend. More technical details on the weather will be discussed below.

First off, today will be a beautiful day. High pressure and confluence from the upper-level low over Southeast Canada will keep a frontal boundary to the south of our region. More high to mid-level clouds over Central and Southern New Jersey are expected to remain closer to the frontal boundary, while sunshine dominates farther north over Northern NJ and NYC. West-southwest winds and deep mixing between 750mb and 800mb will cause temperatures to rise into the lower to middle 70s this afternoon. Breezy conditions also likely this afternoon with wind gusts to near 35mph possible. These winds will also likely hold off any sea-breeze to later in the afternoon, so many coastal locations will see warm temperatures as well.

Premium: Omega block returns, with different results

/by

An anomalous blocking pattern has returned for the second time this Spring, but the sensible weather results will be quite different this time around. Instead of falling underneath a large blocking ridge of high pressure, as we did in early April, this blocking pattern has brought (and will continue to bring) persistent troughiness and unsettled weather to our area, as well as below normal temperatures.

The blocking pattern responsible for the troughiness is quite impressive. Higher than normal height anomalies are present throughout much of the Arctic, including Northern Canada and much of the Northwest Atlantic. This blocking is something that seemingly hid itself during the winter months — which some are certainly thankful for, as its presence would lead to extreme cold and snow. Unfortunately, this time of year, it has resulted in clouds, showers, and temperatures in the 50s for this entire week.

May the 4th Overview: Clouds, Rain, Drizzle…Cut-off Low Woes by Friday

/by

In a galaxy far, far away the weather is probably 1000 times better than it has been here this week. It’s about as miserable as it gets out there. Cold, damp and raw. This all due to omega block, which we’ve been discussing since Sunday, that has set up across over North America this week. While complete washouts aren’t still anticipated, there will be little to force these damp and dreary weather conditions out of the region until the blocking pattern begins to break down this weekend.

Unsettled Weather Continues for The Rest of This Week

/1 Comment/by

A broad wave of low pressure, along a frontal boundary to the south, has caused rain to fall moderately at times overnight and early this morning. Steady rain is now tapering off to more showers , as this storm system consolidates farther offshore. Skies will continue to remain mostly cloudy this afternoon.  Some more widely scattered showers and areas of fog or drizzle are possible, with a couple more weak disturbances and the right-entrance region of upper-level jet streak coming behind this initial low pressure. Clouds and an onshore flow will keep temperatures from rising much today and dropping much tonight — staying in the upper 50’s.
