The Climate Prediction Center has issued their new 30 and 90 day outlooks for precipitation and temperature and the picture for the midwest is unclear. The newest outlooks cover the months of April, May and June. Both the 30 day and the 90 day outlooks have placed most of the central plains in the "equal chance" category. This means that "above normal", "below normal" or "average" conditions all have the same 33% chance of occurring. At this time, there is no meteorological reason to expect a greater likelihood of one occurring more than the other two. This does not mean that "average" conditions are expected, only that "average" or "normal" rainfall and temperatures are just as likely to occur as are "above normal" of "below normal" conditions.
In Lincoln, normal precipitation for April, May and June would total over 10.5 inches. The average high for Lincoln on April 1st is 58 degrees and the average low is 33. By June 1st, the average high jumps to 80 and the average low is 56. In Grand Island, normal precipitation for the 3 month period is 10.4 inches. The average high on April 1st is 56 degrees and the normal low is 32. By June 1st those numbers climb to 78 degrees for a high and 55 for the average low. With the very important spring season arriving, the variability of Nebraska weather will once again take center stage. Stay tuned.
