April 2024 finished up much warmer than normal across much of the Lower 48. However, there is nuance to the temperatures depending upon how you examine the monthly means e.g. minimum, maximum, or average.

The Low temperatures outpaced the highs especially across the Ohio Valley and Midwest. Florida was notably cooler than normal along with the Southwest.

Precipitation and cloud cover largely determines the variability of temperature across much of the U.S. in April as well as the predominant moisture flow either dry out of Canada or moist from Gulf of Mexico.

Of course, a 30-day chunk of the calendar is what we call April but Mother Nature operates on a variety of time scales including daily, weekly and sub-seasonally. During any 4-week period, any location can experience multiple flow regimes so the mean is probably less informative than the variance otherwise known as the weather.

Precipitation anomaly in terms of inches (not %) shows the areas where much above normal rainfall fell including east Texas, Missouri into IL/IN along I-80 into western PA, and the upper-Midwest. A strip of heavy rain also hit the FL panhandle.

However, deficits occurred in the areas in brown.

\"\"

Of course, it\u2019s the actual rainfall amounts that matter especially for the drought indicator.

The Drought dot gov monitor updates tomorrow. But your eyeball can match up the areas of dryness with the April precipitation anomaly map e.g. Iowa is being left out as well as Kansas. The Southeast, Northeast, and Mid-Atlantic are drought-free.

Still an early spring looking pattern with troughs digging into the Western U.S. spawning surface lows across the northern Plains. The flow off the Gulf of Mexico means plenty of moisture and cloud cover for heavy rainfall over the next week across the central U.S. and then slightly weakening as the fronts move eastward.

No heat dome development for the next week.

No surprise about lack of rain across the Southwest \u2014 so the 0% isn\u2019t so important. However, dryness across Florida continues. Otherwise, the Lower 48 is generally wetter than normal over the next 2-weeks.
