Cool Tonight, Sunshine & Warmer Tomorrow

High pressure stretching from the Great Lakes into the Northeast is bringing us nice late summer weather.  As skies clear this evening and winds die down we will have perfect radiational cooling conditions across central New York. Syracuse will see temperatures close to 50 degrees by daybreak which will make it the coolest night we’ve had in more than 2 months.  The record in Syracuse for tomorrow morning is 46 set back in 1988. 

High pressure will still control our weather into tomorrow.  The air mass over us will modify, or warm, so we expect temperatures to end up warmer than today.  By later in the day we will start to see some clouds approaching from our next system. A large trough of low pressure is set up over the East and within this trough a smaller disturbance aloft is now over Iowa.  This disturbance will shoot east over the next 24 hours then move close to central New York later Sunday night into Monday.  Given we are seeing showers and even thunderstorms with this feature right now we are going to increase our chances for wet weather on Monday.

By the middle of the week jet stream winds aloft will start to move back north into Canada.  That means temperatures in central New York will warm back in the 80s just in time for the start of the New York State Fair next Thursday.
