After logging the warmest spring and third-mildest winter in Chicago history, we have a huge likelihood of a warmer-than-normal summer. Yesterday, though, we had one of those perfect days Chicagoans can count on two hands every year: sunny, dry, and 24°C, the kind of day that Parker and I spend entirely outside.
It turns out, a relatively unusual weather pattern could give us more than a week of this sort of thing:
[C]omputer models indicate what is meteorologically-termed an upper-level "Omega Blocking" pattern will establish itself over the United States for the remainder of the workweek. With a trough of low pressure over the east and west coasts and a high pressure ridge over the central plains. This will establish an extensive low-level cool high pressure air mass over eastern Canada into the northeastern and north-central U.S. For Chicago, situated in the southwestern quadrant of the high pressure, it in turn means an extended period of east to southeasterly flow, relatively dry conditions and daily temperatures around normal levels, except cooler readings along the lakefront and beaches.
The official forecast calls for temperatures around 20°C (after 26°C today) and sunny skies through Saturday.
It's all very confusing to us here, all this nearly-perfect weather. We'll just have to muddle through...
