Central and Southern New Jersey remains under a slight risk designation for severe weather. A cold front will be approaching this afternoon and the region is now under the warm sector of a warm front. The clouds are thinning as the satellite imagery indicates across Central and Southern New Jersey. The sunshine is allowing temperatures to spike and increasing the instability. It is now 67 across areas as far north as Burlington County.
While the line of thunderstorms may not look like much now, it is still in areas that have been mainly cloudy and therefore somewhat stable. Once the line enters our region, there is a good possibility it will rapidly intensify. With strong winds aloft, any heavy downpours could pull the wind to the surface and spread it out which would give us a potentially damaging downdraft in spots. High shear may pose an isolated tornado risk. Tornado watches are in effect for the Washington D.C. and Baltimore metro areas and we will have to see if any watches are expanded into our region.
The line is considerably earlier than previous guidance had indicated and the late morning guidance has a weaker line pushing through as a result, but it still shows a fuse being lit as it enters South Jersey and Delaware.
