WASM – The heat wave is set to recede "noticeably and clearly" tomorrow, Sunday, and during the Eid holiday, with temperatures dropping several degrees Celsius. The Kingdom will remain under the influence of the heat wave, but with moderate to weak intensity. Meanwhile, the heat wave's impact will intensify significantly in the eastern and desert regions of the Kingdom, especially on Tuesday and Wednesday, coinciding with "clear" and unseasonable weather disturbances. Temperatures are expected to reach 48 degrees Celsius in some eastern and desert areas.
"Noticeable" temperature drop on Sunday and Monday..
The heat wave will recede "noticeably" on Sunday and Monday, particularly in the western regions of the Kingdom, with temperatures in the capital reaching around 34 degrees Celsius and in the high mountains around 30 degrees Celsius during the day. The weather will be moderate during the evening and night hours, with temperatures around 22 degrees Celsius in the capital and mountains. The heat wave will recede clearly from Aqaba, the Jordan Valley, and the Dead Sea during the Eid holiday, with temperatures near seasonal averages, which remain below 45 degrees Celsius during the day.
Temperature rise on Tuesday and Wednesday, especially in the desert region with "extreme temperature increases"..
Temperatures will rise noticeably on Tuesday and Wednesday, particularly in the eastern desert region of the Kingdom, with the heat wave intensifying in those areas and reaching 48 degrees Celsius in parts of the eastern desert regions.
Temperatures will rise slightly in the western regions of the Kingdom compared to Sunday and Monday, with hot conditions during the day and moderate temperatures at night, with temperatures around 36 degrees Celsius in the capital and 33 degrees Celsius in the mountains.
Heat wave retreat by week's end..
The heat wave will recede completely during the weekend, with temperatures dropping across all regions of the Kingdom and returning to their seasonal averages or slightly below.
Alert on weather disturbances in the eastern desert region..
Coinciding with the heat wave, whose impact will concentrate in the eastern and southern desert regions of the Kingdom, an unstable weather condition is expected to affect the area starting this Saturday afternoon in a limited manner and intensifying during the Eid period. Thundershowers are expected to fall, and dust-raising winds will be active. It is not unlikely that these thunderstorms will extend in a limited and scattered manner toward various regions of the Kingdom, particularly from Monday through the end of the week.
Unseasonable weather disturbances have become a recurring meteorological phenomenon in recent years, coinciding with rising temperature rates in the region and a significant increase in rainfall rates, which may be a result of important climate changes beginning to affect the region.
WASM Regional Center issued a study in 2020 indicating an increase in the impact of strong heat waves toward the Kingdom, coinciding with the occurrence of summer rainy conditions and a significant increase in rainfall rates.
The rise in temperature in the region may be linked with increased rainfall rates, which increase the chances of high evaporation from adjacent water bodies and lower surface atmospheric pressure, as there is an inverse relationship between increased humidity and temperature on one hand and surface atmospheric pressure values on the other. The presence of high latent energy in water vapor and rapid temperature differences trigger thunderstorms and barotropic summer weather instability conditions.
