Once again the focus of our weather this week is closely tied to the the strength of a significant heat dome that resides over the Plains. Fortunately for us, we've been on the eastern flank of the heat where the NW flow aloft has kept the worst impacts to our west. A couple times we've gotten a taste of what could have been but were blessed by the passage of backdoor cool fronts that have kept temperatures and humidity from getting out of control for more than a day or two.
We're in the midst of summer and it's coming with a whole lot of heat this week. Luckily Sunday the humidity dropped and some clouds were in place that allowed for it to feel nicer than Saturday. The heat remains for the week, starting Monday: On Tuesday temperatures go up a few degrees: The humidity also goes up... dew points into the 70s = yuck city: This combination will send heat index values back into the triple digits: Now the issue is even though we can feel the moistu
The hottest weather of the year so far occurred Saturday across the Midwest. The combination of an upper level high pressure system, mostly sunny skies, and an approaching cold front sent temperatures soaring into the 90s. In fact, for many of us this was our first 90° in over a month! Cedar Rapids' last 90° prior to Saturday was all the way back on June 19th. On top of that it felt even hotter with dew points well into the 70s (gross!) Sunday will still be toasty, but it won
If you've been following along lately you know that I've been questioning the strength of a heat wave the models had been advertising for much of next week. The MJO (Madden Julien Oscillation), a teleconnection that often sees trends before the deterministic models, is depicted by both the GFS and EURO to pass through phase 6 during that period. Phase 6 in July portends temperatures that look like this. That's not what you look for in a heat wave. The fact models have not bee
We are rapidly coming up on the anniversary of last years derecho which remains the costliest thunderstorm in U.S. history. The severity of the storm and and its 11 billion dollar damage tab is one of the reasons the NWS is making an important change to its warning system. Starting August 2nd, severe thunderstorm warnings for baseball-size (or larger) hail and/or 80 plus mph winds will activate a Wireless Emergency Alert (WEA) on smartphones. This is to heighten awareness of
