Thanksgiving Climatology & Outlook

The climatology for Thanksgiving dates back at least 110 years to 1907 and since then the holiday is mostly dry and mild. The average high on the holiday is 55° with an average low of 33°. The warmest high took place in 1941 with a sizzling temperature of 75°, while the warmest low of 56° was in 1983. The coldest Thanksgiving took place in 1989 as the high climbed to only 32° with a frigid low of 15°.

Highs above 50° have been achieved a whopping 77% (85/110) of the time, with 50s & 60s being the most common high temperatures  happening about 72% (79/110). Based on those statistics, highs are usually average to above average on Thanksgiving.  However, there has been only 6 times or 5% with highs in the 30s and it’s highly likely this year Salisbury will see its 7th occurrence. Lows on the other hand tend to fall average to below average, with the heavily featured 20s taking placing 44 times or 40%, with 30s happening about one-third of the time.

Measurable rainfall is recorded about a third of the time; with the wettest Thanksgiving taking place in 1983 at 1.82”. The most common amount of rain is typically less than a quarter of an inch of rain. Snowfall is very rare with measurable amounts happening about 3% of the time; with the largest snowfall happening over a century ago in 1912 at 6.0” and the most recent in 1989 at 3.0” for 2nd snowiest.

This Thanksgiving, a strong blast of Arctic air will arrive late on Wednesday night in the form of a cold front and settle in for the holiday.  This batch of air will challenge the record books for one of the coldest Thanksgivings especially in the highs department, as the high temperature will likely take place during the front’s passage overnight on Thursday. A record low maximum will be in the working as the current record for November 22nd is 36° in 1989. Lows will more than likely take place that night in the low to mid 20s by midnight, which will be about 5°-10° above the record low. Conditions however that day will be sunny but with the wind out of the northwest, wind chills will be in the teens and twenties. Stay warm this Thanksgiving, Delmarva!
