Good morning everyone. Chilly air has finally arrived into the Northeast and much of the Midwest & Central States. In the Northeast, lingering lake affect rain showers and a few pellets of sleet remain as cold winds blow across the warm lakes. Meanwhile temperatures in the big cities and coastal regions struggle in the 40's and won't get out of the 50's today. Cool air remains locked in place until the weekend, where 70's return for a few days before the next cooldown.

In the Midwest & Central States, another night of heavy frost and freeze conditions are expected, but we widen the advisory, watch, and warning areas. Freeze warnings stretch from the Dakotas on down into Nebraska, Kansas, and Oklahoma. We'll also watch sub-freezing temps spread across into Iowa, Wisconsin, and Illinois. This cold air mass is far-reaching now, with freeze warnings also in Indiana and Ohio. Look for more of the same tomorrow night and possibly Thursday night as well.

We turn our eyes to Florida where tropical moisture returns to the southern part of the state and the Florida Keys. Our front which is bringing cold air across much of the northern tier, has finally made its way down near the Gulf of Mexico. This will help draw up tropical moisture and set the stage for more scattered heavy showers & thunderstorms across south Florida.

Look for scattered thunderstorms developing today offshore and over land. These storms could be locally strong to severe, with locally strong winds, hail, torrential rain, frequent lightning, and the risk of a few waterspouts. We'll see this action repeat itself tomorrow as well, with the same hazards expected.

Here is your local NYC forecast -

We'll have a mix of sun & clouds today, with highs in the mid to upper 50's at best. We dip into the low 40's overnight tonight, with 30's likely away from the NYC area. Very cool conditions remain tomorrow, with low to mid 50's and another cold night expected.

Temps modify slightly on Thursday with upper 50's returning; then a full modification on Friday with mid 60's. It'll remain cool to cold overnight with low to mid 40's in the City, colder north and west.

Near 70/low 70 temps return on Saturday with full sunshine, and low to mid 70's for Sunday to complete a dry & gorgeous weekend.
