January Climate Recap
Despite some (fairly typical) large swings during January, overall the average temperature for the month ended just a bit above normal. The month started warm with consecutive days in the 60s at the end of week 1, but a cold front brought them back to near average through mid-month. The second half of the month featured more swings from cold to mild with various frontal passages. However, despite the swings, no records were broken with highs mostly in the 40s and 50s and lows in the 20s to 30s. The largest contributor to the above normal average were overnight lows that were about 1.5 degrees above normal, while daytime highs were very close to average for the month.
Precipitation to start 2019 was also a bit above normal, about three-fourths of an inch above the long-term average of nearly 4". Despite having eleven "rain days," most precipitation that contributed to the total fell on just four days that totaled more than one-half inch. Snow fell on the 19th (a dusting that officially was recorded as 0.2") and traces on the 25th and 26th. Overall, a disappointing month for snow-lovers in general! As far as severe weather, three Severe Thunderstorm Warnings were issued for the southern metro as a line of storms swept through early in the morning on the 19th. No damage was reported. On the 23rd, strong southerly (non-thunderstorm) wind downed a large tree in Southaven.
