NYC Weather Update – Aug 22, 2014

We had a solid round of rain from some showers and thunderstorms that passed through the area overnight. Over the weekend, high pressure will start to build into the area, ushering in a period of calm, pleasant, and seasonable weather.

Saturday & Sunday – clouds will diminish later Saturday, and by Sunday we’ll see mostly clear skies. Both days will feature high temperatures around 80.

Monday – as you see below, by Monday an area of high pressure will be firmly entrenched over our region. This high pressure area will persist through the middle of the week, giving us fair conditions and pleasant highs in the low 80s.

High pressure firmly entrenched in the Northeast for the beginning of next week.

Tuesday & Wednesday will look and feel essentially the same with highs in the low 80s and mostly sunny skies.

Our next chance of rain will be later in the week, perhaps Thursday into Friday with the arrival of a cold front from the west.

In the Tropics

There’s a tropical disturbance currently positioned offshore of Puerto Rico that will very likely become the 2014 Atlantic Hurricane Season’s third named storm, Cristobal. You can already begin to see the storm organizing, as over the last day or so, a circulation has become evident, and strong thunderstorms are forming in the northern semicircle are also apparent (see the classic cauliflower tops). Outflow bands are also forming up (thin wispy clouds north and northeast of the center).

This storm will fell some negative impacts from the high terrain of Hispaniola and Puerto Rico. As you can see, the southern semicircle is considerably less organized than the northern.

As for the track of the storm, you can see the rather large spread between the different forecast models, which is not surprising given that the storm is still in its early stages. Note that there is an outlier model solution showing landfall on the Mid-Atlantic. This is unlikely at this point, but worth noting. It seems, given the conditions ahead of the storm, that this will become Tropical Storm Cristobal in the next couple days, and may become Hurricane Cristobal shortly thereafter.

NYC Weekend Weather – Hurricane Arthur – Jul 3, 2014

Lots going on in the realm of weather over the coming weekend. First, to start off with today, the Storm Prediction Center has again placed our area under a slight risk of severe weather this afternoon and evening. We could see a repeat of the type of storms from last night as a cold front makes its approach from the west. Even though temperatures are lower today and sunlight limited, there’s still more than enough instability in the atmosphere to fuel a few strong to severe thunderstorms later today. Because we’re looking at another round of possibly torrential rain from today’s storms, many areas are under a flash flood watch. Part of this moisture is due to the influence of Hurricane Arthur to our south.Untitled3

Hurricane Arthur

As of this morning, Arthur strengthened into the 2014 Atlantic Hurricane Season’s first hurricane and is currently sitting offshore of South Carolina with sustained winds of about 90mph. Forecasters are increasingly confident that Arthur will have enough time over warm water and low wind shear areas to grow into a Category 2 storm before getting recurved out to sea and making extratropical transition.

Track Forecast for Hurricane Arthur

Arthur is now forecast to brush by the Outer Banks of North Carolina sometime later today, and move to just about the 40N, 70W benchmark offshore of the Northeast by 8PM Friday. Given this current forecast track, confidence is increasing that we’ll continue to see heavy rain and showers through out Friday into Friday night, though not directly from Arthur itself. Rather, Arthur will be interacting with that cold front mentioned above to throw a wrench in everyone’s July 4th plans. Conditions should begin to improve rapidly Saturday as Arthur accelerates northeast, pushed by the cold front. We should see a return to sunny skies and seasonable weather Saturday with highs around the low 80s. Of particular concern are areas in Southeastern New England, which could see tropical storm conditions on Friday night into Saturday morning. Any deviation westward of this current forecast track would mean increased impacts on the Northeast, so this storm is worth watching closely. Regardless, high surface and dangerous riptides will be present on all Atlantic shorelines.
