Winter won't give up
As for the Northeast and New England, an active pattern continues this early this spring season, including bouts of winter-like weather. Upper level winds forecast to frequently ride-in from the southwest which typically generates expansive precipitation. Cold air masses, while prevalent in frequency may be short-lived. Not until late in the season will the area experience longer-lasting spells of seasonal temperatures. As for precipitation, normal to above-normal amounts, including late season snowfall is ahead. Fieldwork and planting delays are likely well into the season, along with an increase in spring snowmelt and run-off (flooding) issues.
Finally, across the Midwest and Great Lakes region, southward to the Ohio Valley, a far different winter season compared to that of 2011-2012 generated a wild-ride and range of temperatures and weather, too. This included a wide-range of temperatures as well as no shortage of precipitation, particularly in the eastern Corn Belt. This active pattern will continue, not only regarding the frequency of cold air outbreaks, but the number of weather systems, too. Temperatures will range to below-normal to well below normal, but with some fluctuations from the Mississippi Valley to the lower Ohio Valley. As for precipitation, normal to above-average frequency and amounts are in the offing. The frequency of severe weather outbreaks will also be on the rise across much of the Midwest and Ohio Valley. The recent melting of a sizeable snow cover in parts of the Midwest, along with early through mid-Spring moisture will raise the specter of low-land flooding, fieldwork and planting delays. However, a benefit of this wet pattern will be that of further rises in the Ohio and Mississippi Rivers. Over the remainder of spring, there are signs of a general trend warmer to hotter than-usual conditions, but not necessarily drier.
Potential for long term moisture
Looking ahead briefly into the 2013 late spring and summer season, there is cause for concern as increased dryness and drought issues in the deep southern states, while a re-intensification of drought may be possible on the southern Plains. Meanwhile, a recovery to more seasonal temperatures should improve crop development across the Corn Belt, a trend towards hotter-than-average temperatures will be concern to producers. As for timely rainfall, that looks likely, along with some potential for an ongoing wet pattern, too.
