Lows from the 12th - 17th averaged 13° above normal and from the 24th - 28th, a few degrees higher at 16.5° above normal. Two record high lows were reached on the 26th and 27th. For the Pensacola area, after an overall cool start to the month with regard to low temperatures by a few degrees below normal, two lengthy periods of well above normal high and low temperatures followed. The daily high from the 12th - 17th averaged 8.8° above normal and from the 25th - 31st, 7.6° above normal for these respective periods.

A new record high was reached on the 28th. Summer seemed to come early for a few days of the month at Mobile and Pensacola. Mobile and Pensacola both saw rainfall coming in below normal. Considering annual accumulations, the rain gauge continues to run "dry" with substantial deficits by several inches for both sites so far.

Two record high lows were reached. 72° on the morning of the 26th smashed the previous record on this date of 69° set back in 1949 and also sets the new all time highest low temperature for the month since records have been kept. 71° on the following morning of the 27th broke the previous record on this date of 70° set way back in 1921. The lowest temperature for the month occurred on the mornings of the 4th and the 8th, 36°. (Fig. A) shows a graphical representation of how the Mobile area temperatures compared to the seasonal 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 the table below (Figs. B and C). Total rainfall for March (Fig. D) measured only 5.72", 0.42" below normal. The annual rainfall to date shown in (Fig. E) is shy of 6.0" below normal.

April 2021 Climatology, Seasonal Climatology and Outlooks:
Important: NOAA will be updating the climatology dataset to a "New Normal". The new 30-year dataset will span from 1991 to 2020 and is scheduled for release in May 2021. For more information on the roll-out, refer to the following link from the National Centers for Environmental Information (NCEI 30 Year Normals 1991-2020).
As we move deeper into Spring, the latest outlook for April favors about a 40% probability of seeing above normal temperatures over the southeast US and coastal plain. With spring gardens underway, keep in mind there can still be instances of cold weather which could see the thermometer plunging to at or below freezing or bouts of frost. Both will be detrimental to sensitive outdoor plants and measures to protect them will need to be in place if the need arises. A link to the latest drought information and outlooks are included in the table below. We are moving into the height of severe weather season too and information on severe weather climatology is posted as a link.

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. To learn more click on the CoCoRaHS link below.
