Wow! What a difference a few days makes in our local weather. We started this week with accumulating snow. Then there was the wind and cold on Monday and Tuesday. Thanks to a major shift in the weather pattern, the sun has returned and temperatures are MUCH warmer. In fact, temperatures are near record highs! Here are the record high temperatures over the next several days:
11/5 - 71° (2015)
11/6 - 76° (1948)
11/7 - 74° (1945)
11/8 - 77° (1938)
11/9 - 74° (1938)
11/10 - 74° (1931)
Why has the weather changed so dramatically? The answer has to do with the change in the jet stream. The jet stream is a strong moving wind located high in the atmosphere. The jet stream is responsible for steering the storm track and determining which locations will see above average temperatures and which will see below average temperatures.
There are two basic patterns to the jet stream - a ridge and a trough. A ridge is a crest in the jet stream and favors warm, sunny weather. A trough is a dip in the jet stream and favors cool, unsettled weather. Our current weather pattern across the country has a MAJOR ridge that spans from almost coast to coast. This type of pattern is expected to last for the rest of the week, weekend, and early next week. Eventually the ridge will break down as cooler weather dives into the Western US. That cooler weather looks to arrive as early as the end of next week.
