Today’s blog will only be a mini-blog because I’m up against it time-wise. Normally I keep Monday clear but today that wasn’t possible so I’ll do a full blog later this week on Thursday with the GDD analysis for June as we are now in a new month, July. (Thanks again to everyone for sending in their data)
Last week’s promised rain materialised but didn’t give as much for some as was forecast and that’s because the low pressure become more easterly-orientated as it progressed up from the south coast. So here in The Midlands we ended up with 12mm when 22mm was forecast and somewhere across in the east like my beloved Wells-next-the-Sea in Norfolk, ended up with 33mm. The dividing line was once again the A1 and I’ve said this before, those Romans knew a thing or two about the weather when they built that road where it is. For sure they did.
You can see how the rain progressed in these screen shots I took from Netweather’s rain radar service.
So how are we looking this week ?
Well here’s my summary synopsis for the week ahead..
This week we have a battle between an Atlantic low and a Bay of Biscay high and that means a great deal of uncertainty about yes you guessed it, rainfall. I think the majority of rain will be west and north this week with it not moving into central areas until Friday.
So for central and southern areas including The Midlands, we should have a pretty dry week with temperatures building as the week progresses culminating in the mid-high twenties by the end of the week before thunderstorms and rain moves in from the west on Thursday / Friday to freshen up the weather in time for the weekend. For Wales and the south west of England, more chance of showers on Monday and Tuesday mornings but staying mainly dry after this with again heat building towards the end of the week, into the mid-high twenties possibly. Thursday p.m. looks like when it’ll be due to break down into thunderstorms and these will continue with more rain across Friday. For the north and north west of England, you’ll catch more of the low pressure system so cooler here with more cloud cover and rain. Showers kicking off on Monday but a heavier band of rain is due on Tuesday to move across the north of England during the day. Drier through Wednesday, still with the threat of showers and then more rain from Thursday and Friday as the low pressure becomes more dominant. For Ireland, showers for you on Monday giving way to a heavier pulse of rain on Monday night that will push up country and become heavier as it does so. This rain will continue on Tuesday but really only affecting the top half of the country from Dublin north probably. Wednesday looks dull initially but brightening up from the south west to give clear spells of sunshine and pleasant temperatures probably into the low-mid twenties for Wednesday and Thursday. By then we could see some more showers move into the east of the country but I think although you’ll be more unsettled by the end of the week you’ll miss most of the U.K’s rain. Finally Scotland, unsettled during Monday with rain clearing from the north to give a largely dry day on Tuesday though that heavy band of rain may flirt with The Borders and east of Scotland later in the day. Dull with some showers on Wednesday, clearing through the morning to give a pleasant day but much cooler here with mid-high teens the order of the week as the weather is more influenced by the cooler low pressure system. As we approach the end of the week we see more unsettled weather pushing through on Thursday / Friday.
At present (I’ll update on Thursday) it looks like we’ll keep the warmer, settled conditions starting next week but cooler than the high’s of this week with low twenties more typical. Towards the end of next week, a northerly low presure system is due to push down and influence the weather from the north first so that means cool and unsettled with rain for Scotland and the north of England. At this stage it looks like it could push down and affect southern and central areas by next weekend but that’s along way off so we’ll see when I update on Thursday.
With the combination of high temperatures in late June and then rainfall, it’s not surprising that pretty much everything comes out of the woodwork from a turf perspective.
For instance, I noticed the first burst of etiolated growth late last week on some collars and approaches together with a whole host of other maladies.
I’ll concentrate on two for today.
Temperature + rainfall is the combination for Superficial Fairy Ring (shown below) and its many variants so a lot of rings around many of which are likely to be caused by this family. That said there are other pathogens, like Waitea Patch and even Ectoparasitic nematodes which can cause similar symptoms so the best way to determine what you’re dealing with is to take a core from the ring.
Have a smell for any musty, mushroom like odour, a sure give-away for Fairy Ring and then take the core, put it down on its side and then place water droplets on it to see if they go into the profile or bead up. (see above). If they do then it’s very likely that you have hydrophobicity caused by this disease and this may in turn be affecting turf performance. I did this last week and found hydrophobicity down about 50mm below the surface. In this case you’ll need to spike the area, apply some wetting agent and if it is really a concern aesthetically, a fungicide as well.
Waitea Patch (below) can look very, very similar to Superficial Fairy Ring but there’s some important differences. There doesn’t tend to be the musty, old socks type of smell, there’s no hydrophobicity and it is really affected by moisture. So it tends to appear after heavy rain and / irrigation and typically on wetter areas of greens. Thankfully both pathogens are usually controlled by the same fungicide, Azoxystrobin, so if your I.D is off, it may not be such an issue.
Ok that’s all for this week’s mini-blog, as stated above, I’ll do a more in-depth one on Thursday and by then we should see how those storms are progressing and whether next week’s low pressure is a certainty or a flash in the pan.
All the best.
