Drought Busting Rainfall

Two systems will spread more much needed rainfall across the region. The first will move into the region this afternoon with rain spreading from west to east between 11AM and 1pm and ending from west to east between 5-8pm. Can’t rule out some onset freezing rain across the highest peaks of the Catskills above 2500’s this afternoon.  Here’s a look at the projected radar this afternoon and what we should expect for total rainfall from this first system. A general .20” to .40” with some higher amounts across the southern and eastern facing slopes of the higher terrain.

Our next system will pack a bit more of a punch,  precipitation arrives Tuesday night around midnight and continues into Thursday night before ending. Rainfall with this system will fall heavy at times on Wednesday into Wednesday evening. This rainfall will be the result of a slow moving cold front that will have some waves of energy moving along it, this will result in a somewhat long duration of unsettled weather. Rainfall with this system will range anywhere from 1-2” with some locally higher amounts in our favorable terrain areas.
Above is the GFS projected rainfall for the second system, so a total rainfall from both systems of 2-3”, which will take a significant chunk out of our rainfall deficit. The bigger story with this system will be the colder air on the backside, as this frontal boundary crashes east so will colder air. As the final area of low pressure passes east of our region, colder air will be advecting in from the west, this will turn rain to snow across western parts of our region on Wednesday night. Just how far east the rain/snow line will progress will depend on the speed of the frontal boundary. Here’s a look at what the surface map may look like on Wednesday evening.
This could lead to some travel woes late Wednesday into Thursday AM as some accumulating snow may fall across western parts of the region. In addition, even areas that miss out on a few hours of wet snow, the cold air will sweep into the entire region. So areas that had just received 1-2 inches of rain will drop below freezing quickly on Thursday morning and a flash freeze is likely. So aside from the incoming rainfall, quick hit today and a longer duration event beginning tomorrow night, be aware of the risk for accumulating wet snow west of the river and across higher terrain,  and a flash freeze that will impact the entire region for the Thursday AM commute. Here’s a look at wake up temps Thursday after the rainfall.

We will continue to monitor the data and have more updates over the next day or two. Have a great start to your week.
