A strong area of low pressure is expected to develop later this week across North Dakota or adjacent south central Canada. A cold front is likely to trail south of the low through the western Plains states. Meanwhile, high pressure is predicted to drift off to the southeast from the Great Lakes area into the southern Appalachian Mountains. Between the two pressure centers a rather stout southerly wind regime along with very warm to hot temperatures is likely. These winds are likely to originate in Texas where corn earworm moths are likely active, and a few moths could migrate north into especially the Plains states or southwestern corn-growing region by late week and into the weekend. Low migration risks are in the forecast both Thursday night into Friday night mainly across Kansas, Nebraska, western Iowa, and western Missouri, but the risk has been extended slightly further east to near the Mississippi River Friday night into Saturday morning. No additional risks are in the forecast at this time.
