December 2022 in Review - December was a month of wild temperature extremes characterized by an extended period of summer-like conditions for the first two weeks. Followed by the passage of a series of strong cold fronts, the temperature story changed markedly to one that trended much colder. The strongest of the frontal passages occurring Thursday night December 22nd brought a period of downright frigid temperatures to the deep south, just in time for Christmas. For the Mobile area, the month began anomalously warm when daily high temperatures averaged 10.0° above normal and lows averaged 14.1° above normal the first 14 days. During this span, Mobile saw five new record daily highs being broken or tied and one morning where the low tied a record high low. Entering the second half of the month the thermometer went the other direction, when daily highs averaged 9.8° below normal and lows 9.9° below normal from the 17th to the 27th. Within this period, the lows from the 23rd to the 26th alone averaged a phenomenal 20.0° below normal. For the Pensacola area, daily high temperatures averaged 8.8° above normal and lows averaged 13.4° above normal the first 14 days. During this span, Pensacola saw five new record daily highs being broken or tied and one morning where the low tied a record high low. Entering the second half of the month, colder as well where daily highs averaged 9.2° below normal and lows 10.2° below normal from the 17th to the 27th. Within this period, the lows from the 23rd to the 26th alone averaged a phenomenal 21.7° below normal at Pensacola.
Monthly rainfall at Mobile was shy of normal by a little over a half inch while Pensacola just made it above the monthly normal by nearly a quarter inch.
Mobile Alabama Area [Climate Normal Period 1991-2020, Climate Record Period 1872 to Present]- Despite, the arctic plunge in temperatures the start of the last quarter of the month, monthly temperatures were above normal by a few degrees due to the longer duration of well above normal temperatures the first of the month in addition to the recovery from the cold the last few days of the month. The average monthly high of 65.6° was 2.1° above normal. The average monthly low was 47.1° or 4.1° above normal. The average monthly temperature of 56.3° was 3.0° above normal. Now for the extremes. The highest temperature for the month, 85°, occurred on the 7th. This was both 20° above the normal for the date and set not only a new daily record high, but also the highest temperature in the Mobile area for the month of December. In addition, Mobile saw four other record highs being reached or tied and on the morning of the 6th, 66° tied a record high low. For the lowest temperature, Christmas Eve morning saw the thermometer plunge to 20°, an astounding 22° below normal for the date followed by the high which only reached 37°, an equally astounding 25° below normal for the date and only 5° from reaching a new daily record low high temperature for December 24th. (Fig. A) shows a graphical representation of how the Mobile area temperatures compared to the monthly normal daily highs and lows, which are shown by the colored dashed lines. Bar graphs reflecting the daily high/low temperature departures from normal are provided in (Figs. B and C). The breakout of temperature records are listed in table format (Fig. D). The rain gauge collected 4.80" (Fig. E), or 0.65" below normal.

2022 Severe Weather: NWS Mobile storm survey teams verified the occurrence of a record setting 55 tornadoes impacting the National Weather Service (NWS) Mobile County Warning Area (CWA). This number stands alone as the most confirmed tornadoes in a single year since official storm event records have been kept since 1950. The previous record of tornadoes in a single year was 39 tornadoes back in 2011. The image below shows the number of occurrences of tornadoes in 2022 sorted by (Enhanced Fujita Scale (EF) Rating. The verified number of EF1's and EF2's also stand tall in the record books. Note: There was one event that was classified as unknown given the overlapping paths and likely similar starting points with another verified tornado occurring in eastern Crenshaw county on April 5th. It was impossible to determine what the true intensity, path width, path length, and end point of this tornado was.
Details of each survey are provided in the Past Significant Weather Events link.
Additional December 2022 Climatology and Topics
The bulk of the rain through the month of December was observed in a narrow swath from southern Mississippi to coastal southwest Alabama into the western Florida Panhandle. Highest rainfall departures to above normal were focused over coastal Baldwin county in Alabama and the southern portions of the western Florida Panhandle where between 110 to 150% of normal rainfall was distributed. Fig. K shows the areal monthly rainfall total, Fig. L shows the areal rainfall departures from normal and Fig. M, the areal percent of normal rainfall. The latest December 2022 monthly summary for Eglin Air Force Base (AFB) - KVPS and Duke Field - KEGI has been received and provided in the table below. The temperatures in the daily tables consists of numbers both in °F/°C. Data courtesy of Mr. David Biggar, Staff Meteorologist, 96th Weather Squadron. Provided by permission.

Additional Climate Links:
The links below are intended to provide additional climate information, education and outlooks. The National Weather Service Mobile Alabama's Climate and Past Weather page provides climate data at your fingertips for many observation points in the local forecast area by accessing the NOWData tab as well as many other climate resources. The Climate Prediction Center Link provides short and longer range climatic outlooks and education about the larger scale global circulations that impact temperatures and weather. With the large agriculture and farming presence along the central Gulf coast, the Drought Monitor link provides updates on drought trends and impacts. Another very helpful resource is the Community Collaborative Rain Hail and Snow (CoCoRaHS) network, which is a large group of volunteers working together to measure and map precipitation (rain, hail and snow). The aim of CoCoRaHS is to provide the highest quality data for natural resource, education and research applications. You can be a part of the CoCoRaHS team by becoming a volunteer rainfall observer.
