021 FNUS71 KPHI 070943 FWSPHI Spot Forecast for Gap Fire...PA DCNR National Weather Service Mount Holly NJ 443 AM EST Thu Nov 7 2024 Forecast is based on forecast start time of 0800 EST on November 07. If conditions become unrepresentative, contact the National Weather Service. Please contact our office if you have questions or concerns with this forecast. .DISCUSSION... A cold front will move through the region later this morning, and a drier airmass will spread into the region this afternoon. Surface dew points drop from the upper 50s to low 60s early this morning to the 40s to low 50s for most of the area this afternoon, except for Delmarva, where it will take some time for the drier air to arrive. It will still be warm with highs in the 70s to near 80. This results in MinRH values generally 35 to 45 percent. Northwest winds will increase this afternoon to 10 to 15 mph with 20 to 25 mph gusts. Winds diminish fairly quickly after sunset this evening. For Friday and Saturday, daytime minimum relative humidity values are forecast to range from 25 to 35 percent. Westerly winds increase to 10-20 mph with gusts 25-30 mph during the day Friday, then gradually diminish Friday night. A lighter northerly wind is forecast for Saturday. Given the continued very dry conditions and increased winds, there is an increased risk for rapid fire spread on Friday. Showers are forecast to result in a wetting rain later Sunday into Monday. Continue to follow burn restrictions and check with your state and local fire officials for more information .REST OF TODAY... Sky/weather.........Sunny (10-20 percent).
