NYC Weather Update – Jun 25, 2014

A warm and humid day out there in the Tri-State this afternoon. You can feel it’s potential thunderstorm weather. In fact, the Storm Prediction Center has issued a mesoscale discussion (analysis of weather conditions conducive to severe weather on a medium scale – 10km-500km). Very moist air, warm temperatures, combined with a slowly approaching cold front set the stage this afternoon for possible development of strong to marginally severe thunderstorms. This is especially the case over inland areas, as depicted below. In general, expect a line of showers and maybe a couple thunderstorms to pass through the area later this evening into the overnight areas when the cold front finally pushes through.

Thursday – there could be some lingering showers in the AM, but things will dry out quickly and clouds will slowly give way to sunnier skies. High temperatures will be a bit cooler than today, in the upper 70s to low 80s.

Friday – a splendid end to the work week with mostly sunny skies and comfortable, less humid conditions and temperatures in the low 80s.

Saturday and Sunday will both again feature excellent weather as a high pressure system works its way over our region following this cold front. As the high pressure slowly slides to the southeast, it will bring us southerly winds that will usher in another period of warm and humid weather. Saturday will be the better day of the weekend with high temperatures in the low-mid 80s and lower humidity. By Sunday, temperatures will begin ramping up into the mid-80s with an increase in humidity. Early next week, we’ll be looking at a continuing warming trend with high temperatures in the mid-upper 80s Monday and near 90 Tuesday before our next chance of rain.
