If you have been reading my articles over the years you know I have a few weather pet peeves. This article’s pet peeve is probably on the top of my list as I hear it discussed again and again, and people just don’t seem to properly understand this topic. So, even though I seem to
Measuring atmospheric moisture not easy
Relative humidity has to be one of the most misunderstood terms in weatherspeak
Forecast: More showers, then sunny and dry
Forecast issued Monday, July 15, 2019 covering July 17-24, 2019
Once again, the weather models did a pretty good job with the forecast. The heat and humidity moved in last weekend as expected and we did see several rounds of thunderstorms move through on Sunday and Monday of last week. This forecast period will begin fairly unsettled as a broad area of low pressure tracks
Forecast: Warm and unsettled weather lays ahead
Issued July 8, 2019: Covering the period from July 10 to July 17
Last week’s forecast played out pretty close to what the weather models predicted. For this forecast period it looks like the area of low pressure that brought the unsettled, stormy weather to much of southern and central Manitoba during the first half of this week will have finally moved off to the east. Weak high
Can we expect late-June’s heat to continue?
Eastern Manitoba missed out on most of the large-scale rain events we saw last month
We’ve been stuck in a weather pattern that has been giving us colder-than-average temperatures since last January and this pattern really didn’t break down in June. We continued to see upper lows getting blocked over either northern Manitoba or Hudson Bay, with only a couple of short periods where this pattern broke down. June saw
Forecast: And now, your fairly quiet forecast
Last week’s forecast played out fairly close to what the weather models predicted. If we see the same thing for this forecast period, expect mostly sunny skies, maybe the odd thundershower, and temperatures right around average for early July. This forecast period will begin with a large upper low dropping into northern Manitoba from the
Forecast: Warm with the chance of storms
Issued June 24, 2019: Covering the period from June 26 to July 3
I’m not sure if I should say this, but it looks more and more like last weekend’s upper low may have finally broken the pattern of colder-than-average temperatures we have been in for several months now. As with all pattern changes, we will have to see if the new warmer pattern can stick, or will
Blocking patterns and summer heat waves
Consistently warm weather may follow if this blocking pattern breaks down next week
To begin our look at summer heat waves, with a hope of possibly breaking this cold weather pattern we seem to be stuck in, I thought we should begin by looking at blocking patterns. In early May I talked about upper-level lows, and these blocking patterns can often be associated with these upper lows. We
Forecast: Unsettled, unpredictable weather pattern
Issued June 17, 2019: Covering the period from June 19 to 26
Well, last week’s forecast turned out not too bad, considering this annoying weather pattern in which we seem to be stuck. The weather models seem to be having an OK time handling the large-scale features, but are struggling with the day-to-day details. This forecast period looks like it will be another tough one to figure
Is that a cold air funnel or a tornado?
Super cell thunderstorms, from which tornadoes usually develop, are tough to predict
In this article, we continue our look at severe thunderstorms, and specifically the most deadly part: tornadoes. What are tornadoes and how do they form? A classic definition of a tornado is a violently rotating column of air that extends from a thunderstorm to the ground, and which may or may not be visible as
Forecast: A cool start, then summer returns
Issued June 10, 2019: Covering the period from June 12 to 19
On the good news side of things, the weather models were pretty accurate with last week’s forecast. The western low developed as forecast and followed the predicted northerly track over the weekend. It did bring in warmer-than-expected air last Friday, with some areas of central and eastern regions seeing daytime highs pushing 35 C. The
