March Climate Recap
Temperatures for the month of March in Memphis averaged 0.9 degrees above normal, though that departure was driven exclusively by overnight lows averaging more than two degrees above normal due to extensive cloud cover and precipitation. Those same conditions actually resulted in daytime high temperatures averaging below normal for the month. March started out with highs in the 70's, followed by a cold front on the 8th that pushed highs into the 50's & even upper 40's by the 13th. After a brief warm-up, another reinforcing front resulted in highs in the 40's and 50's from the 18th to 22nd and lows dropping into the mid 20's on the 19th and 20th, freezing many early blooming plants. Highs rose back above normal to the 60's to 70's for the remainder of the month, with lows in the 40's and 50's.
March's precipitation was almost three inches above normal and totaled nearly nine inches for the month. Overall, rain fell on almost half of the days during the month with a few rounds of severe weather mixed in as well. Over three inches of rain was recorded from the 1st to the 3rd. Additional rain fell from the 8th thru the 12th, 16th-17th, 21st-22nd, and 1.6 inches fell on the 24th. Light amounts fell from the 27th through the end of the month. Thunderstorms occurred on the 1st-3rd, 12th, 24th and 31st. Sporadic wind damage and flash flooding were reported across the metro on the morning of the 3rd and the evening of the 24th. Hail was also reported in northern Marshall County on the evening of the 1st.
To end the month, a severe weather outbreak, producing multiple strong tornadoes from a small handful of supercell thunderstorms, affected the Memphis region on the evening of March 31. A total of 14 tornadoes touched down in the Memphis County Warning Area (CWA), which encompasses west TN, northeast AR, the Missouri bootheel, and north Mississippi. Three of these tornadoes were rated EF-3 and another five were EF-2. The graphic below summarizes their tracks. More information from the NWS can be found here & in our recent blog post here.
