Last August had big rain at the beginning of the month, then below normal rainfall for the rest of the month. So I think there will be less of a chance of a long stretch of big heat. That trend will also keep our heat from building. This year, more opportunities will mean more than normal rain chances. Like July, August will have more rain opportunities.Įarly August last year, we had another big storm that brought another 5” of rain, but then we were generally dry for the next several weeks. That will be something to monitor for the next few months. Honestly, I don’t think we will really see all the effects of the El Niño pattern until we get to winter. But remember the advertised pattern switch, both locally and globally? That may be evident this August. Keep the sprinklers handy.Īugust is normally when you start to say, “Ok summer, I need a break.” We look north for cool fronts or south for some soaking rain, and neither really get here.Īugust is typically hot and dry.
We will have some opportunities for rain, but not all will get as much as they need. I think the dry pattern of the last few weeks will continue into June. I’ve seen more sprinklers running in the last few weeks because of this. So, we need rain.Īsk your lawn or garden. The drought severity across Missouri is heightened just a bit because of this. April and May have trended dry and our yearly average for rainfall is running a little bit short. We begin June a bit behind the eight ball. However, it could also bring a quieter hurricane season.īut what does that all mean to St. Forecast precipitation across Texas verified below what was anticipated, and towards the end of June a substantial heat dome developed and is favored to persist through the first few weeks of July. It also could bring a heightened risk of droughts and floods and stronger storms. Updated Seasonal Assessment - Two significant pattern changes drove the end-of-month revisions to the July-August-September seasonal drought outlook. The last Super Niño pattern was in 2016, and we saw the warmest global temperature on record. That sounds pretty ominous – and it could be. And there are some indications that this pattern could be what’s called a Super Niño. We are moving from our third La Nina year to an El Niño pattern.
LOUIS – We are in the middle of a major global pattern change. In this situation, the loss of the high pressure will give way to cooler winds from the north-west, bringing rain from the Atlantic with them.ST. Sadly, that doesn't mean we're in for a particularly mild winter. "At the moment, the high pressure is slinking away to the west and allowing a north-westerly wind to come in and take over," says Hardy. If the high pressure remains where it is, we could be in for a cold winter, but there are already signs it is moving on. Since mid-July a high pressure system has dominated Britain's weather, leading to few days of cloud and rain. The result is a colder winter, so long as the high-pressure weather system doesn't move on. "Without the cloud, you lose the blanket that keeps the ground warm at night," says Hardy. With no cloud cover, the heat radiated from the ground over the longer nights escapes, making the land cool more than usual. If the high-pressure system persists into the autumn and early winter, the clear skies also continue as the days get shorter, giving long, cloudless nights as winter approaches. High pressure systems force air downwards and, since rain clouds typically need rising air to form, the skies above high pressure systems usually remain cloud free. A long, hot summer means a high-pressure weather system has been lurking overhead or nearby.
