Post-Labor Day weather-maker items feature heavy tropical rain in the U.S. midsection, freeze chances in the western Canadian Prairies,
and an iffy rainfall pattern in Russia's wheat country.

First, the tropical rainfall situation. The National Weather Service is calling for Tropical Storm Hermine to produce total rainfall accumulations
of 4 to 8 inches, with possible isolated maximum amounts of 10 inches from the middle Texas coast northward through central Texas and over
central and eastern Oklahoma. These rains are expected to spread across southeastern Kansas, northwestern Arkansas, and Missouri during the next
few days and could cause life-threatening flash floods.

There is also a chance that the heavier Hermine-related rain could make its way into southern Illinois and the Ohio Valley. If that pans out, we could see some harvest delays for at least a few days.

Also, a Reuters article today notes that some light frost occurred in the Canadian Prairies last weekend, and the western Prairies (Alberta province) could have some hard-freeze temperatures next week. W. Canada harvest 18 pct done, major frost seen next week. This occurrence would arrive with less than 20 percent of the harvest done in Canada--of course, planting last spring was delayed extensively by heavy rain and flooding.

Fortunately for crops--indications are that most wheat and barley should be mature enough by next week to avoid frost damage. Prairie farmers have harvested 18 percent of their crops, well behind the normal rate of 31 percent for this time of year, according to the Canadian Wheat Board.

And in Russia, the official weather service says that sporadic rains on Sept. 7-9, will cool the air in the Southern and North Caucasus federal districts to 20 degrees Celsius (68 Fahrenheit) from 28-29 degrees.

But the level of precipitation will be just 5-6 millimeters (around 0.2 inches), which is insufficient for successful winter grain sowing. The wheat areas need at least an inch.

The best time for the start of the winter sowing campaign in the northern part of this region is the beginning of September, while in the south the sowing may prove successful if it starts before the middle of October.

Elsewhere in Russia, local rains are expected also in the Urals and Siberia, with daily temperatures falling to 8 degrees (about 50 deg Fahrenheit) from 25.

Night frosts of between minus 1 to minus 5 degrees are expected in the northeast of the Central federal district and in the north of the Volga district, as well as in the Urals and in the country's far east.
