Slow Moving Low Pressure

Areas across the middle section of the country continue to pick up the pieces after a blitz for tornadoes on April 9, 2015. The preceding day was expected to be the most dangerous but the most violent weather struck Northern Illinois last Thursday. Thankful the weather in that section of the country is much quieter than last week. A large upper level low pressure spun possibly two dozen tornadoes across the southern plans yesterday but none appeared to be violent or deadly. Locally the weather has largely been quiet and warm. Weak cool fronts have moved through during the week not alter temperatures whatsoever. Above normal temperatures will continue through the weekend before a cut-off low pressure brings a prolong period of cool and unsettled weather for much of next week.

The most violent and deadliest tornado of the year so far struck Northern Illinois on April 9, 2015. It was one of approximately two dozen tornadoes that struck that day. The total number of tornadoes for that and the previous is approximately thirty (30).

Currently the local area is under the influence of high pressure. Skies are currently clear and high temperatures are well into the sixties. A strong and slow moving low pressure is over Eastern New Mexico and is generating heavy snow for the Colorado Front Range and severe weather across Central Texas.

On Saturday the low will move very slow to the north and will once again generate severe weather across the Central and Lower Plain States. This will allow nice weather to continue locally with high temperatures approaching the seventy (70) degree mark. Conditions on Sunday will be similar but the area of severe weather will shift eastward and be centered on the Lower Mississippi River Valley.

On Monday the storm system will continue to move slowly eastward and will spread showers and possibly thunderstorms to the local area. Timing of the rain is uncertain but temperatures may approach seventy (70) again if the rain holds off for much of the day.

Tuesday will start the cool, wet and unsettled period for the area. A low pressure system will stall over the Great Lakes region and cause much cooler conditions for the area. Conditions will be mostly cloudy throughout the period but peaks of sunshine will also occur. High temperatures will be below normal and will not rise much above the middle fifties (50’s) from Tuesday through Friday.
