NYC Weather Update – Oct 30, 2017

NYC, Weather Update, , , , ,

Crisp fall weather is in place for the start of this work week on the heels of yesterday’s strong storm. Winds abate today but temperatures turn noticeably colder tomorrow. A gradual warming trend is anticipated later this week with highs pushing back towards 70°F.

Rest of today – as the low pressure responsible for yesterday’s storm continues to pull away from us to the north-northeast, the pressure gradient will relax and result in lower wind speeds. These winds will bring with them a much cooler Canadian airmass (via cold advection) and high temperatures should be in the mid-50s.

Map of analyzed values of cold advection (transfer of heat, or in this case, lack of heat). The blues and purples indicate areas of increasing intensity of cold advection, where temperatures are falling by as much as 2ºF an hour. The causative agent of the cold advection in the Northeast are the winds associated the departing storm.

Tuesday – sunny skies, a sparkling fall day with high temperatures in the mid-50s again.

Wednesday – partly sunny with high temperatures in the mid-50s.

Thursday – a return to warmer temperatures in the mid-60s with us in the warm sector between a retreating warm and advancing cold front.
