The National Weather Service is looking for a cold start to the week, followed by a surge of tropical moisture Wednesday. The tropical moisture is from the remains of Hurricane Patricia being swept up into the midwest United States. The latest runs of computer models have sped up the transport of moisture and bring a steady rain into our area on Wednesday, ending as showers Thursday morning. The moisture will be swept out by a cold front bringing drier air from Canada. The front is likely not to produce measurable rain as it comes through. As the Philadelphia office says….
THE GFS GAVE UP THE GHOST ON PASSING THE SHORT WAVE TROF THROUGH OUR CWA ON FRIDAY, SPEEDING AND WEAKENING THE PROCESS TO THURSDAY NIGHT. BY THEN THE AVAILABLE MOISTURE WOULD NOT SUPPORT PCPN MAKING IT INTO THE GROUND. NOTHING FRIGHTENING ABOUT HALLOWEEN SATURDAY AS IT CONTINUES TO LOOK MOSTLY SUNNY WITH NEAR SEASONABLE TEMPERATURES.
