Memorial Day Weekend Outlook
Onshore Flow Questions
Mainly Dry Through Sunday..Questions for Monday
Before we get to the holiday weekend let’s look at the short range. The satellite loop shows the twisting upper low and the developing clouds offshore to our south and east. Low pressure is developing there and that low will move northward tonight with the upper air low. The result will be an increasing clouds late this afternoon and tonight. We should not have any showers for the evening commute. Overnight some rain or showers will be developing and backing in from the east.
You can see the beginnings of the rain on the radar developing to the southeast so we will watch as it expands and makes its way northward. Showers will develop after the evening commute and then continue on and off overnight into the first part of Tuesday. Then weather conditions will improve Tuesday afternoon and Wednesday will be a much better day with sunshine returning and highs well into the 70s. If the west wind holds, Northern Nassau and Northwest Suffolk will reach the 80s! Thursday and Friday look good too with some sunshine and highs reaching into the 80s before any sea breeze hits.
Now with regards to the holiday weekend, beginning on Friday we should be okay and I think we should be okay through the daytime Sunday with clouds and some sunshine. Highs will be in the upper 70s to lower 80s with local sea breezes developing at the beaches. We will have a separate beach forecast for you as we get closer. Sunday night models are suggesting a back door front may move through which will make Monday cooler (if this is right) and also might bring in cloud issues.
Memorial Day Weekend Outlook
GFS MODEL MONDAY MORNING 2AM
The other issue for the Memorial Day Weekend Outlook surrounds the development of low pressure east of the Bahamas that moves northwestward. Weather models are all over the place with this and given the time of year it is always possible that this could be some sort of tropical system though the time of year would argue against that. We will of course keep a watch on this as the week progresses. It should be noted that the Euro model is slower and develops the low much later in the forecast period. It also does not show a well developed backdoor front like the other models do. For now we will be optimistic on the overall weekend until we see how this all winds up playing out.
