Central Alabama Rainfall - How are We Doing This Year?

(Updated through July 28th)

 

There have been some hot, dry days this summer in Central Alabama, but there have also been periods that we have received some fairly substantial rainfall.  So, how are we doing so far rainfall-wise? Let's check a few Central Alabama stations and see.

 

 

2015 Yearly Rainfall to Date and Comparison to 2014 Rainfall

Station

2015 Rainfall through 7/28 (Inches)

2015 Departure from Normal (Inches)

2014 Rainfall through 7/28 (Inches)

Difference 2015 vs 2014 (Inches)

Birmingham 34.67 +1.95 28.59 +6.08
Anniston 32.00 +0.80 29.20 +2.80
Tuscaloosa 29.46 -2.73 31.11 -1.65
Calera 36.45 +3.60 36.03 +0.42
Montgomery 28.99 -3.32 36.34 -7.35
Troy 26.56 -6.24 34.97 -8.41

We can see some trends from the table above. First, stations along the Interstate 20 Corridor from Birmingham eastward have generally received more rain so far this year than at the same time in 2014. However, most other areas are generally running below their rainfall totals for the same period in 2014, especially in the southeastern sections of Central Alabama where rainfall is around seven and a half to eight and a half inches less than for the same period in 2014.

So, what does the remainder of the year look like, rainfall-wise?  In the near-term, it appears that fairly normal late July weather is on tap with plenty of heat and periods of scattered showers and thunderstorms, especially in the afternoon and evening hours.  The Climate Prediction Center's outlook for Central Alabama for the August through October period is for equal chances for below or above normal rainfall, with equal to above normal chances forecast for November into January.  With a developing El Nino pattern expected to persist into the fall and possibly winter season, this would be a normally expected pattern for Central Alabama.

So, all of this suggests that Central Alabama will likely escape major drought conditions in 2015 and end the year with fairly normal rainfall.

 

New Monthly Rainfall Record at the Shelby County Airport in Calera

 

An additional note of interest.  At the Shelby County Airport in Calera, the July rainfall total to date for this year is now 10.22 inches following 1.07 inches that fell on the 28th.  This  exceeds the previous record July rainfall for the period of record dating back to 1995 at the Shelby County Airport which was 9.94 inches, set in 1995.  And with a couple more days left in the month, and more scattered afternoon showers and thunderstorms expected, it is possible that this month's total could go higher.
