Indiana has been very dry the last several weeks (Figure 1) and conditions are starting to show in lawns and fields. This dryness has been exacerbated by low humidity and warmer temperatures (Figure 2). After a nice respite this past weekend, temperatures will start rising again into the weekend, but may not seem too uncomfortable[Read More…]
Climate and Weather
The month of May was sprinkled with a record-breaking freeze over Mother’s Day weekend, followed by heavy rainfall the following weekend, with a roller coaster of cool periods and extremely warm periods. We often think of spring as being that transition between winter and summer with lots of ups and downs, but those extremes from[Read More…]
Two weekends ago, Indiana was facing freezing temperatures that broke numerous records across the state. This past weekend into early this week, the story has been lot of rain. As of the morning of Wednesday, May 20th, the northwest counties have received over 4 inches with a northwest to southeast gradient of decreasing amounts down[Read More…]
Strawberries growing in the matted-row system are in the blooming stage. Open flowers cannot tolerate temperatures lower than 30°F (Figure 1). Strawberry growers should be prepared for the coming low temperatures this week. Row covers (Figure 2) can be effective in protecting strawberry flowers. In our earlier trial, 1.5 oz/sq row covers provided 4-6 degrees[Read More…]
The Climate Prediction Center’s outlook for May is dominated by uncertainty regarding both temperature and precipitation (Figure 1). The computer models could not settle on a consistent pattern for either above- or below-normal temperatures for the month and precipitation outlooks are only slightly confident that there will be above-normal precipitation in southern Indiana. Shorter-term outlooks[Read More…]
Two types of injury on young warm-season vegetable plants are caused by low temperatures: frost/freezing injury and chilling injury. Frost/freezing injury occurs when temperatures drop below 32°F. Ice formation in plant tissue cuts cell membranes. When the tissue thaws, the damage results in fluids leaking from the cell, causing water soaked damage. Frost/freezing injury is[Read More…]
Staying true to global climate trends these days, March 2020 finished warmer and wetter than the 1981-2010 climate normal period. Snowfall across the state was below normal and localized flooding was a common feature. There were 3-to-5 more days than average in March where rainfall was observed. This has led to saturated soils throughout the[Read More…]
Meteorological winter (December-February) is finally over and we can start looking forward to spring. Across Indiana, winter brought above average precipitation (Figure 1), though below average snowfall. The temperatures were slightly above normal (2°F-6°F; Figure 2) with no record-breaking cold periods. Since there were so few colder-than-normal periods, the overwintering of pests and therefore increased[Read More…]
When I was very young, I remember my father talking about “knee high by the Fourth of July”. As I got older I thought that expression was so strange for it seemed the corn was usually “man high” by the Fourth of July. Obviously, the excessive rains and cooler temperatures have had an impact this[Read More…]
So far for the month of May, temperatures across the state vary by nearly 2˚F above normal in the southeast and almost 3˚F below normal in the extreme northwest. Similarly, the same trends can be seen in the Modified Growing Degree Days as they are based on temperature (Figure 1). The main story continues[Read More…]
