In April, the length of the day increases, there is a further accumulation of heat. In the north of Kazakhstan, there is a steady transition of the average daily air temperature through 0 ° to positive values. Snow cover in April in most of the territory is destroyed.
At the beginning of April, spring will come into its own in the northern regions of Kazakhstan: it will warm up significantly and the weather without precipitation is expected. In the west of the country, with the influence of a cyclone from the Black Sea, there will be rains with gusty winds. Already from the middle of the first decade, the cyclone, moving in an easterly direction, will cause the unstable nature of the weather in the rest of the republic. Precipitation (rain, snow) - mainly in the northern regions, thunderstorms are forecast in the southern regions. Fogs, icy phenomena and increased wind with gusts of 15-20, on some days up to 23-28 m/s are expected in most of the country.
At the beginning of the first decade of April, it will warm up:
in the west of the republic at night from +1+9°From to +3+12°C, during the day from +7+15°C to +15+22°C;
in the north, north-west, east of Kazakhstan at night from -5+3 °C to 0,+7 °C, during the day from +2+10 °C to +5+13°C.
in the center of the country at night from 0,-5 °C to +2 +7 ° C, during the day from +6+11 ° C to +13+18 °C.
In the middle of the first decade of April, with the influence of an anticyclone, a short-term decrease in air temperature is expected in the west, northwest and north of the country. The temperature will drop at night to -5+3 °C, during the day to +3+10 ° C.
However, in the southern and southeastern regions of the republic, during the first decade, night air temperatures are expected to rise at night to +8+13 ° C, and daytime air temperatures will fluctuate during the day from +15+23 ° C to +20+28 °C.
Often in the second and third decades of April, warm air masses will arrive on the territory of Kazakhstan from the regions of Iran and Central Asia, which will cause an increased background temperature: in the northern half of the day +15 +23 ° C, in the southern +28+35 ° C. But despite the high temperatures, mainly in the western regions and in the northern half of the country, with the passage of atmospheric fronts, unstable weather is predicted. Precipitation is expected (rain with a transition to snow), blizzards, fogs, icy phenomena, gusty winds up to 28 m/s are likely. In the southern half of the country, precipitation is also expected on some days (mainly in the form of rain), in mountainous and foothill areas, with a decrease in air temperature, snow is also possible.
Such phenomena as thunderstorms, hail, dust storms are typical for April.
In the middle of spring, relatively cold days are not excluded, with a significant decrease in air temperature. With inflows of cold air masses, in the northern, central and eastern regions of the republic, the thermometer columns can drop to 0,-9 °C at night, to +3+8 °C during the day, to -5+7 °C at night in the southern regions and in the west of the country, to +10+15 °C during the day.
Note: the forecast for the month should be used as an advisory, which is subsequently adjusted as the synoptic situation changes and is clarified by weather forecasts for the decade.
