Wednesday, November 13 Observations:

11.13.13As the strong cold air mass entered the region, the coldest temperature of the fall so far were observed. Morning low temperatures were generally in the 20s across the area, with the first freeze for locations that haven’t experienced it yet up to this point, with a low of 29 degrees in Central Park. Mostly sunny skies were observed during the day with unseasonably cold high temperatures, peaking in the mid 30s to low 40s across the area. The highest temperature was 41 degrees in Newark, NJ and JFK airport, and the lowest high temperature was 36 degrees in Danbury, CT.

Tuesday, November 12 Observations:

11.12.13Read more: Nov 12, 2013 Morning Update

The first widespread snow event of the winter of 2013-14 affected the area on Tuesday, as a strong cold front moved through in the morning hours, bringing a much colder air mass into the region. High temperatures were observed early in the day, towards 12-3 AM, peaking in the upper 40s to low 50s; the highest temperature was 53 degrees in multiple locations, and the lowest high temperature was 46 degrees in Port Jervis, NY.

Precipitation lagged behind the frontal passage, which occurred around midnight, which along with strong cold air advection allowed for a changeover to snow in the morning. Scattered showers developed around 2-4 AM. Northern NJ, SE NY and southern CT changed over to snow between 5-7 AM, with NYC and Long Island changing over between 7-9 AM. Snow was generally light, but with locally moderate bursts of snow especially east and south of NYC. Snow totals were generally up to a coating, but with accumulations up to/locally over 1/2 inch reported in Long Island and CT, locally as high as 1-2 inches in Connecticut; the highest total was 2 inches in Ridgefield, CT (Fairfield county). Snow gradually ended around 9-11 AM from NW to SE, with mostly cloudy skies continuing through the afternoon, clearing by the evening. Daytime temperatures generally held steady in the mid 30s to low 40s, with low temperatures occurring at midnight.

Monday, November 11 Observations:

11.11.13Another transient cool air mass quickly moved through the region, having entered on Sunday afternoon with a duration of less than 24 hours as a southwesterly flow resumed on Monday ahead of an approaching strong cold air mass. Temperatures were slightly cooler than those of Sunday, peaking in the low to mid 50s, with a lower than average temperature range across the area of only 4 degrees. The highest temperature was 54 degrees in multiple locations, and the lowest high temperature was 50 degrees in multiple locations.

Sunday, November 10 Observations:

11.10.13A low pressure moved through northern New England, producing scattered rain/snow showers well to the north as a cold front moved through the area in the afternoon. The frontal passage was expected to be dry, but scattered showers unexpectedly developed and accompanied the frontal passage, with rain amounts below 0.05 to 0.1 inch. Temperatures early in the day were warmer than expected, peaking in the upper 50s to low 60s, but cooled down by the afternoon with increasing winds associated with the frontal passage. The highest temperature was 63 degrees in Westhampton Beach, NY, and the lowest high temperature was 56 degrees in Andover, NJ.

Saturday, November 9 Observations:

11.9.13Partly cloudy skies were generally observed on Saturday, but with increasing clouds late in the day as a transient high pressure moved through the area with a low pressure approaching New York state by the evening, removing the transient cool air mass. Temperatures were similar to those of Friday, peaking in the upper 40s to low 50s across the area. The highest temperature was 55 degrees in Montauk, NY, and the lowest high temperature was 46 degrees in Danbury, CT.

Friday, November 8 Observations:

11.8.13Partly sunny skies were observed behind Thursday’s cold front as a transient colder air mass entered the region, with a breezy west wind at 10-15 mph. Colder than average temperatures returned across the region, peaking in the mid to upper 40s inland and the low 50s from NYC and further east and south. The highest temperature was 52 degrees in JFK Airport and New London, CT, and the lowest high temperature was 47 degrees in multiple locations.

Thursday, November 7 Observations:

11.7.13Another weakening cold front moved through the region as Wednesday’s Midwest low pressure quickly tracked northeast into Canada, with occasional morning and afternoon showers amounting to less than 1/4 inch for most of the area. Central Park recorded 0.15″, making it the 5th largest rain event of this fall so far, and offering little help to end the dry pattern, with a moderate drought covering NYC, Long Island and southern CT. Temperatures were warmer than average again, peaking in the low 60s for most of the area. The highest temperature was 64 degrees in multiple locations, and the lowest high temperature was 58 degrees in Sussex, NJ.

Wednesday, November 6 Observations:

11.6.13As a low pressure tracked northeast through the Midwest, producing a rain/snow storm, ridging built over the region with a warmer air mass returning into the area. Partly to mostly cloudy skies were observed with temperatures returning to above average levels, peaking in the upper 50s to mid 60s across most of the area. The highest temperature was 65 degrees in Somerset, NJ, and the lowest high temperature was 58 degrees in multiple locations.

Tuesday, November 5 Observations:

11.5.13As the strong high pressure shifted east of the region, the cold air mass exited, with temperatures failing to drop after midnight; Westhampton Beach, NY fell from 44 to 28 degrees on Monday evening in just 2 hours, but quickly went back up to the mid 30s by Tuesday morning. High temperatures generally peaked in the mid 50s with partly cloudy skies. The highest temperature was 57 degrees in Somerset, NJ, and the lowest high temperature was 51 degrees in New London, CT.

Monday, November 4 Observations:

11.4.13As the cold air mass reached its southernmost extent and a high pressure built into the region, mainly sunny skies were observed on Monday with cold morning temperatures, reaching 19 degrees in Sussex, NJ and Montgomery, NY, but only 35 degrees in Central Park. Daytime highs generally peaked in the mid 40s across the area; Central Park’s high of 46 degrees was 12 degrees below average. The highest temperature was 48 degrees in JFK Airport and New London, CT, and the lowest high temperature was 43 degrees in Sussex, NJ.

Sunday, November 3 Observations:

11.3.13The second cold front moved through early in the day, producing little rain but with colder temperatures entering the region, bringing the coldest air mass of the fall to date. Widespread cloud cover was observed with high temperatures generally peaking in the mid to upper 40s inland and the low to mid 50s from NYC and further east and south. The highest temperature was 53 degrees in multiple locations, and the lowest high temperature was 43 degrees in Port Jervis, NY.

Saturday, November 2 Observations:

11.2.13The cold front from Friday stalled east of the area overnight as a wave of low pressure developed offshore, then continued to progress east on Saturday. Partly sunny skies were generally observed with temperatures remaining warmer than average, generally in the mid to upper 60s, as a second cold front approached but with little to no rain. The highest temperature was 69 degrees in Meriden, CT, and the lowest high temperature was 63 degrees in New London, CT.

Friday, November 1 Observations:

11.1.13

A low pressure rapidly intensified over the Great Lakes while tracking northeast into Canada, bringing a cold front through the region. The strongest forcing remained well to the north of the area, with minor rain amounts generally below 1/4″, near 0.19″ in NYC, locally up to 1/2 inch west of NYC, which was still the most significant rain event in nearly a month (October 7). The most significant aspect of this storm was the wind, however, as a narrow squall line moved through the area between 9-11 AM, producing strong wind gusts locally over 40 mph in northern NJ with reports of wind damage. Otherwise, temperatures were unseasonably mild, peaking in the mid 60s to low 70s across the area. The highest temperature was 71 degrees in Newark, NJ, and the lowest high temperature was 64 degrees in Farmingdale, NY.
