Coldest air of the season arrives & lasts all week, no tropical storms or hurricane risks ahead

It is a mostly quiet weekend in much of the Eastern & Southern US as the weather continues to remain relatively calm from tropical storm or hurricane activity. Ignore rumors about future storms, there are no risks to the East Coast or the Gulf Coast through next week. Today is a sunny day through most of this region including Eastern Pennsylvania to Southern New England. Temperatures will be warming up into the 70s as the high temperature map above below. Radars are nice and quiet with no rain around today or tonight.

An east west cold front will approach Sunday with a low running along that front from the Ohio through NY State and New England. This will brings some clouds in later tonight and more clouds for Sunday The front is relatively moisture starved in areas to the south of it so there isn't much in the way of any rainfall. There could be some showers and scattered thunderstorms ahead of it and there might be some isolated severe thunderstorms in the central Appalachians.

This low will strengthen in Eastern Canada Sunday night and Monday and it will help to draw southward very chilly air into the eastern half of the US and that includes areas in Deep South and the interior Southeast US. This will be a week where many areas will experience their first frosts and freezes of the season with the exception of larger urban areas as well as coastal areas.

The frontal boundary will make it all they way south into the Gulf of Mexico spreading dry air into the Gulf as well as Florida. This action with a large dome of high pressure will prevent any tropical storm development in this region. While there are indications of a tropical system developing in the Southwest Caribbean later next week it will probably stay south and perhaps impact the region in Central America and not be a risk to the United States.

There will be a bit of wide range in temperatures Sunday with areas from Philadelphia and NYC northward being in cloud cover for much of the day. Highs in the region with clouds will be in the mid to upper 60s while Southern New Jersey and Southern Pennsylvania southward will see highs in the 70s as these areas will have some sun in the mix. Showers and an isolated thunderstorm are possible Sunday night as the front passes but it won't do much as far as rain is concerned.

The front is gone by Monday morning and the day will be one of leftover clouds with developing breaks of sunshine. A gusty northwest wind will develop. North and west of coastal areas highs will be in the mid to upper 50s while the coast will top out in the 60s early in the day and temperatures won't be moving much. Cold 40s will be the norm Tuesday morning along the coast and warmer urban areas with 30s inland.

Tuesday and Wednesday will be the two coldest days this week. Sunshine and patchy clouds are forecast Tuesday and Wednesday. Daytime highs everywhere will not get out of the 50s. Tuesday night into Wednesday morning and Wednesday night into Thursday morning will be the two coldest nights with morning lows in the 40s along the coast with numerous 30s inland and some areas will likely break below freezing. Depending on wind and location there will be frost and freeze issues.

Thursday and Friday will be dry and sunny with highs both days back into the 60s. We will probably warm up nicely next week with highs back into the 70s in most places and it looks like the next cold front will not approach until Monday. That could be the next chance we see some rain or showers. Another chilly shot of air is likely to follow into the middle of next week. There are no signs that the dry pattern we are in will come to an end anytime soon.
