More weird weather on the way!

May, a month that is supposed to be dry, one month away from June, the start of summer, will start with a fresh and strong round of thunderstorms and rain over central and NW Arabian Peninsula.

A deep low (typical of late winter) will pass over Turkey and cooler air into northern Arabia, resulting in explosive thunderstorms over a large part of Saudi Arabia. Western Yemen, Kuwait, Bahrain, and Qatar are also at risk of these thunderstorms. Rain and thunderstorms will also extend to much of Iraq and western Iran. The middeteranian countries and Egypt might also be getting some showers and a few thunderstorms.

God help Saudi Arabia from these monsterous thunderstorms! The probability of flood is there!

Rainfall during the next 7 days. Purple spots indicate heavy rain

Rain in Riyadh

Thunderstorms were forming on more or less a daily [...]]]> April proved to be really wet across a large part of the Arabian Peninsula, mainly over much of central Saudi Arabia and Yemen. Kuwait, Bahrain, and Qatar have also been affected by periods of thunderstorms.  Iraq and western Iran also got periods of heavy rain/showers/thunderstorms.

Rain in Riyadh

Thunderstorms were forming on more or less a daily basis for at least 3 weeks. And this is not reaching an end yet, thanks to abundant equatorial moisutre coming and weak upper troughs!

But how much rain really fell?

The first map below shows rainfall accumulation/day during the last 30 days. Well, Saudi Arabia got more rainfall than France or Germany! It seems that rainfall was between 50 and 250 mm. And SW Saudi Arabia was hit hard by around 200 mm of flooding rain, which resulted in fatalities.

Tropical moisture continues to flow into Arabia, and lows continue to drift over SW Asia, inducing thunderstorms formation over Yemen, Saudi Arabia, Kuwait, Iraq, and Iran. During the next 7 days, it will be the same with effects possibly reaching Bahrain and Qatar.

There are hints that early May will also show a similar pattern; however, that will be extremely abnormal given that May is a very dry month and summer is on the way

Latest forecasts is calling for heavy thunderstorms to form during the next 7 days (at least) on the middle section of the Arabian Peninsula. Saudi Arabia, Qatar, Bahrain, and Kuwait are likely to experience sudden heavy thunderstorms, albeit scattered most likley. The UAE and Oman has a smaller chance later this week.

Iran and Iraq are also prone to showers, rain, and thunderstorms!

 

 ____________

An unusual weather pattern is setting over the Arabian Peninsula. Hot weather has already taken over; however, tropical moisture is flowing abundantly via the equator, coupled with a week upper low. All of this is already resulting in some thunderstorms over Saudi Arabia and Kuwait. Again on Monday, these thunderstorms will gain power and continue forming randomly making threats to Yemen, Kuwait, Saudi Arabia, Qatar and Bahrain. Starting Tuesday, the UAE and Oman will be exposed to the potential development of such thunderstorms until Friday.

Stay tuned for more updates

Saudi Arabia is prone to heavy thunderstorms especially April 9 and 10. Thunderstorms could also hit Kuwait, Bahrain, Qatar, and a smaller chance for the UAE and Oman on Sat. Rain showers will also hit Iran and Iraq.

Saudi Arabia is prone to heavy thunderstorms especially April 9 and 10. Thunderstorms could also hit Kuwait, Bahrain, Qatar, and a smaller chance for the UAE and Oman on Sat. Rain showers will also hit Iran and Iraq.

During the next 7 days, scattered thunderstorms could form daily across parts of Arabia, mainly central Saudi Arabia.

At the same time, its cold front will extend to parts of the Arabian Peninsula, bringing the risk of thundershowers to Kuwait, Qatar, Bahrain, and especially Saudi Arabia [...]]]> An upper-air low is tracking eastward over Iraq and Iran, causing rainshowers and thunderstorms over many areas in the Middeteranian countries, Iraq, and Iran during the next 48 hours.

At the same time, its cold front will extend to parts of the Arabian Peninsula, bringing the risk of thundershowers to Kuwait, Qatar, Bahrain, and especially Saudi Arabia near the shores of the Arabian Gulf. By Sunday, the weak cold front arrives to the eastern gulf near the UAE, bringing in scattered clouds and a small chance of thundershowers. Before the arrival of the cold front, it will be very hot in the UAE.

Once again on Tuesday and Wednesday, an upper air trough could result in some thunderstorms in Saudi Arabia, Bahrain, Qatar, possibly Kuwait, and the UAE. Afterthat, there is the potential for high winds and cooler air.

An upper low is currently over the middeteranian countries which brought rain showers and thunderstorms there including some heavy showers to Egypt. There are also rain and thunderstorms over parts of Iraq, Iran, NW Saudi Arabia and Kuwait.

Surface lows and fronts on Fri Feb 26 2010

An upper low is currently over the middeteranian countries which brought rain showers and thunderstorms there including some heavy showers to Egypt. There are also rain and thunderstorms over parts of Iraq, Iran, NW Saudi Arabia and Kuwait.

Currently hot weather with southerly winds are affecting the UAE & Oman. It feels like summer here in the UAE with temperatures hovering in mid 30s. Right now the cold front (blue) is unable to cause any rain/thunderstorms formation due to interaction with dry air. On Saturday/Sunday it will result in thunderstorms and rain showers over many parts of the UAE (especially north) and northern Oman (Slight chance of rain in Bahrain and Qatar). Some thunderstorms could be strong. Rainfall amounts could be anywhere between 1 to 25 mm.  

Spring starts on March 1st, 2010 with a collision between summer and winter with heavy rain and thunderstorms in the UAE.

The cold front that has swept through the UAE and Oman generated a widespread cloud cover with showers in some parts of the UAE. However, in northern UAE especially in Ras Al Khaymah heavy thunderstorms produced heavy rain and flooded the wadis there, resulting in 2 casualities and forcing the authorities to rescue more than 300 people stranded in RAK Wadis. Rainfall amounts exceeded 60mm in some parts of RAK.

Later the cold front entered Oman and produced widespread rainfall and some heavy storms. Rain extended from northern to southern Oman (Salalah) which rarely receives winter rain. Similar to what happened in the UAE, 2 people died in Oman with many being stranded in Wadis.

The cold front also produced a few showers in Qatar, Bahrain, and Saudi Arabia before affecting the UAE & Oman. Heavy rain also fell over the Arabian Gulf and Gulf of Oman.

As the cold front left the region, cooler and gusty conditions (around 50 Km/hr in Bahrain) took place with colder nights with Sharjah airport recording 8c at 7AM on Feb 9, 2010. Other gulf countries experienced cold conditions as daytime temperatures struggled to exceed mid teens.

Shamal winds (winds blowing from North, or NW ) have already started blowing and will increase in intensity during the next 48 hours. A few highlights:
