A poor excuse for a cold front moved through central New York this afternoon. Our winds shifted into the northwest but we won’t have much of a chance to cool down as the front will start to move back north as a warm front overnight. That puts us back into southerly winds and a hot air mass tomorrow. The heat and humidity may spark an odd shower or thunderstorm in the afternoon. With winds in the lower atmosphere solidly out of the south showers and storms will move from south to north on the radar screen, not west to east as is typical. Even though there will not be many thunderstorms tomorrow, those that do form may have gusty wind and very heavy rain. Any relief from thunderstorms tomorrow afternoon will be temporary.
Sunday will likely be the third day of 90 degree weather as winds increase from the southwest, officially making this stretch of hot weather a heat wave. The increase in wind speed will result from a strengthening area of low pressure that is forecast to move through southern and eastern Canada. Additionally, the cold front associated with the low will extend south from its center and is forecast to impact the region on Sunday afternoon and Sunday night. With the hot and humid air in place and strong winds aloft we’ll need to keep a sharp weather eye on thunderstorms Sunday afternoon and evening. Some of the storms could have strong winds and hail.
In the wake of Sunday’s cold front look for cooler and less humid air to arrive Monday with warming temperatures possible next Tuesday and Wednesday.
