After a warmer than normal March the weather pattern will shift back to a cooler pattern at the beginning of April. An upper level trough over eastern North America will produce northwesterly flow for much of the first two weeks of April. The northwesterly flow will bring cooler air from Canada. As weather systems move from west to east across the U.S., we will get some warm days, but on average the temperature will be slightly cooler than normal for April. Northwesterly flow tends to bring drier air. Several storms systems will bring significant rain during the month, but the precipitation is likely to be slightly below normal for April.
