• Mid-continental atmospheric blockage patterns will keep major weather systems stuck in place over the next week, with rising temperatures in Chicago inside warm-air building domes and a rain-free Memorial Day weekend setting. will be arranged.Temperatures are rising daily here, with highs expected to exceed 90 degrees next Tuesday, Wednesday and Thursday
  • The most important rule of thumb in forming atmospheric blockage patterns is what is happening across the central United States. It means that controlled weather systems are likely to continue while the disruption pattern is in progress. Blocking patterns slows down the weather system by its very nature.
  • For Chicago and the Midwest, we’re stepping right into the middle of a vast Canadian high. Friday afternoon had a low relative humidity of 22%, the driest weather for the time of year. Due to the dryness in the center of the high, rain is expected for the foreseeable future, including Memorial Day weekend, with the dry pattern continuing into next business week. It will be.

Patchy frost hit parts of the cold northwestern suburbs Friday morning

  • High-pressure south-northeast winds are bringing the chill we felt on Thursday and night. Frost-level coldness in colder areas off Lake Michigan north and west of Chicago shifted south of Chicago Friday morning.
  • These set the stage for massive wind-driven precipitation events. Heavy winds will continue for several days, including thunderstorms, and strong winds will send huge ocean swells that could lash the Atlantic coast of the Carolina for several days. .

Cool down and go from week to week

  • High-pressure south-northeast winds are bringing the chill we felt on Thursday and evening. Frost-level coldness in colder areas off Lake Michigan north and west of Chicago shifted south of Chicago Friday morning.
  • The warming dome that develops over the Midwest over the next week may retrograde (move westward) as the interception pattern breaks later next week and next weekend, causing cooler temperatures over the next weekend and into next week. .

  • Temperatures made a nice recovery from the chilly Friday morning, with patches of frost in parts of the northern and northwestern suburbs. Lows are normally 54, but dropped to 45 in O’Hare and 50 in Midway.
  • However, inland temperatures hit 33C in McHenry, 34C in Richmond in McHenry County, and 34C in Odell in Livingston County, with Friday morning lows in northwestern Indiana interior in Chesterton, Indiana and Michigan. 36°C in City.
  • Friday was as sunny as it was dry with 100% sunshine possible for May. Solar power generation for the month was nearly 20% higher than normal. At the same time, this is 11% of normal rainfall, and only 0.42 inches of rainfall so far compared to 2.68 inches of normal rainfall so far. May is coming to an end Wednesday midnight as Chicago’s second driest May in 153 years.
  • warming has begun. Today’s highs of nearly 70 degrees Celsius are eight degrees warmer than yesterday, and the warming is set to continue through the upcoming Memorial Day weekend, where no rain is expected until late next week at the earliest. Even if it rains, it will not be very impressive.
  • In fact, model estimates of rainfall over the next two weeks look insignificant. One estimate for the period through Friday 9 June says rainfall will be less than a quarter of normal and dry conditions could last five or more weeks.
  • As indicated for the past few days, the numerical model forecast continues to build a REX-BLOCKING pattern featuring a dome of warm air that deflects moisture, and will continue well into next week. The effect of such a block is essentially to confine a large weather feature to its location. An anticyclone blankets our region, suggesting that air masses are likely to stagnate in place and warm slowly but steadily over the next week. The maximum temperature in Chicago would then be 75°C on Saturday, 80°C on Sunday, and 84°C on Memorial Day (Monday).
  • Over the weekend, the air will remain dry with dew points in the high 30s to high 40s. Dry air cools down at night, so we expect cool nights and warm days this weekend.
  • Over the weekend, the air will remain dry with dew points in the high 30s to high 40s. Dry air cools down at night, so we expect cool nights and warm days this weekend.
  • One interesting forecast trend is an increase in mostly high clouds after Saturday’s sunny start. High cloudiness will persist by the end of the day and can extend into Sunday morning. But after Sunday’s overcast start, those high clouds are parting to reveal a mixed sun, and Memorial Day is expected to clear up. These clouds are therefore not expected to impede the gradual warming that has begun.
  • Lake breezes will cool coastal areas each day of the week ahead, but easterly winds will pick up next weekend and into the week ahead. This suggests that warming will push temperatures up to within 90 degrees inland in the Chicago area next Tuesday, Wednesday and Thursday. However, the intensity of these easterly winds will be weaker than in recent days, which could limit the distance the lake’s cooling can travel inland.
  • Sailors planning to head out to Lake Michigan over the weekend will encounter a one-foot chop as the expected easterly winds don’t cover the long-lasting waters like the north-northeast winds of the past few days. It’s a long stretch of rough seas, but it doesn’t happen on weekends.
  • This blocking pattern is bad news for some parts of the Atlantic coast, especially Carolina. In Carolina, strong easterly winds across the vast stretch of water in the Atlantic will bring rain to the coast over the weekend and huge waves lashing the coastline. Precipitation estimates indicate that two to six inches of localized rain could flood parts of large parts of Carolina.
